You land at Henri Coandă International Airport, grab your bag, and walk past the currency exchange bureau near the arrivals exit. The board shows 4.5 lei per euro. You keep walking. Twenty minutes later, at the Universitate metro station kiosk, the same board shows 4.95 lei per euro. That spread—nearly 10%—is the difference between a guidebook that works and one that costs you money.

Romania is not an expensive destination. A meal in Bucharest runs roughly 30–50 lei, a metro ticket 3 lei, a decent hotel room 200–300 lei. But the small costs add up, and the biggest hidden tax is the currency exchange you do in the first hour. Lonely Planet's Romania guide, for example, recommends using ATMs or bank branches for cash—advice that ignores the subway kiosk, a mundane, reliable workhorse that beats both.

This is not a complaint about Romania. It is a case study in how the most practical travel information lives outside the glossy features. The same logic applies to SIM cards, drinking water, and bag storage. The airport premium is not just a markup; it is a trap for the unprepared. And the fix is almost always a five-minute walk to a kiosk.

The €20 Trap at Henri Coandă Departures

The bureau de change at Henri Coandă sits in the arrivals hall, staffed by a bored teller. On a recent Tuesday afternoon, the board read 4.50 lei per euro for cash. At the Universitate metro kiosk, 45 minutes later, the rate was 4.95. For a traveler exchanging €200, that is an extra 90 lei—about €18. For a family of four, the difference covers a full dinner. Why does the airport rate stink? Because the teller counts on urgency. You just landed, you need local cash for a taxi or a snack, and you have not researched alternatives. The spread is pure profit. Romanian banks, by contrast, average around 4.98 lei per euro, according to ING data from late 2024, but bank branches close early and often charge a small commission. The subway kiosk offers a rate closer to the interbank mid-rate, with no commission and no minimum. The trick is to bring enough euros from home to get you to the city center. A bus ticket from the airport to Gara de Nord costs about 3 lei, paid by card or a few coins. Once you are at a metro station, the kiosk is your best bet. Do not exchange at the hotel front desk either—rates there are often worse than the airport, sometimes as low as 4.3 lei per euro. Some travelers argue that using a credit card avoids the problem entirely. Romania is card-friendly in cities, but cash is still king for small purchases, market stalls, and rural areas. A card transaction also carries a foreign transaction fee of 1–3%, plus the card network's spread. The subway kiosk cash exchange remains the cheapest option for getting lei in your pocket.

Subway Kiosks: Unlikely FX Desks

Bucharest's metro system has about 40 stations, and most major transfer hubs—Universitate, Unirii, Victoriei, Piata Romana—have a kiosk near the ticket office. These are not dedicated exchange counters; they are convenience stores that also sell snacks, newspapers, and phone credit. But they display a yellow sign with the current euro and dollar rates, updated hourly. The process is simple: hand over your euros, get lei in return. No passport needed, no forms, no commission. The limit is roughly €500 per transaction, which covers most travelers' needs. The kiosks are open from around 7 a.m. to 10 p.m., seven days a week. The rate fluctuates with the market, but it is consistently within 1–2% of the official rate—far better than the airport's 5–7% spread. However, there is a catch: the kiosk attendant might not accept torn or very old euro notes. Bring crisp, clean bills. Also, the kiosk does not give change in small denominations—you might get a 100-lei note for a €20 exchange. That is fine for larger purchases, but keep some coins for the metro ticket machine, which does not accept bills. If you arrive late at night, the kiosk may be closed. In that case, use the ATM at the airport—but only one from a major bank like BCR or BRD, and withdraw a small amount to cover the taxi. The ATM fee is typically 3–5% plus a flat €2–€4, so a single large withdrawal is better than multiple small ones. But for most arrivals, the subway kiosk wins on rate, convenience, and transparency.

Why Travel Blogs Get Romanian Currency Wrong

Search for "how to exchange money in Romania" and you will find two recommendations: use ATMs, or find a bank. Both are half-truths. ATMs charge fees that eat into your cash, and banks close at 4 p.m. and are rarely open weekends. The subway kiosk, which is faster and cheaper, appears in almost no mainstream guide. The same blind spot applies to exchange houses in the old town, Lipscani. These storefronts advertise "0% commission" but hide the spread. A typical Lipscani exchange house might offer 4.75 lei per euro while the kiosk gives 4.95. The difference is buried in the fine print. Travel blogs, which often rely on affiliate links for hotel bookings, have little incentive to dig into currency logistics. Another myth: "The leu is stable, so just use your card." The leu fluctuates—it lost about 5% against the euro in 2024—but that is not the point. The point is that the exchange rate you get varies wildly by venue. A card transaction uses Visa or Mastercard's rate, which is fair but includes a 1% conversion fee plus your bank's foreign transaction fee. For cash, the kiosk is king. Some travelers swear by the Romanian Post Office, which also exchanges currency at decent rates. But post office hours are limited, and queues can be long. The subway kiosk is faster, more accessible, and more consistent. The lesson: ignore the generic advice, and look for the mundane infrastructure that locals actually use.

The Paperwork Reality That Catches Arrivals

Currency exchange is not the only bureaucratic wrinkle. Romania requires foreign visitors to register with local authorities within 24 hours of arrival. Hotels do this automatically, but if you are staying at a private apartment or with friends, you must fill out a registration form and submit it to the nearest police station. Failure to do so can result in a fine of 500–1,000 lei. Another catch: customs declaration for cash. If you enter or leave Romania with more than €10,000 in cash (or equivalent), you must declare it. The form is available at customs kiosks. Undeclared cash can be confiscated. This is standard EU policy, but many travelers from outside the Schengen area do not realize it applies. For large purchases—say, a piece of art or a carpet—keep the receipt. Police can ask to see proof of purchase, and without it, the item may be considered illegally exported. The rule is rarely enforced, but it exists. Similarly, if you buy a SIM card, you must present your passport. No exceptions. The kiosk clerk will photocopy it. None of this is onerous, but it catches people who assume Romania operates like Western Europe. The paperwork is a five-minute task, but ignoring it can cost time and money. The subway kiosk, again, is a good place to ask about local rules—the attendants often speak some English and are used to tourist questions.

SIM Cards: Orange vs Digi at the Kiosk

The same subway kiosk that exchanges your money also sells prepaid SIM cards. Orange and Digi are the two main providers. An Orange prepaid card with 10 GB of data and 30 days of validity costs 5–8 lei. Digi offers 5 GB for 3–5 lei, valid 7 days. Both require a passport for activation, and the kiosk clerk will handle the registration in about five minutes. At the airport, a similar SIM card costs 15–20 lei—double or triple the price. The airport shops know you need connectivity immediately. But if you can wait 20 minutes until you reach the city, you save money. The subway kiosk also sells top-up vouchers, so you can add data later without a trip to a phone store. Coverage is generally good in cities and along major highways. In rural areas, Orange has a slight edge over Digi, but both work for basic navigation and messaging. If you need a local number for calls, the prepaid card includes a Romanian number with cheap rates to EU countries. One tip: buy the SIM card at the same time you exchange money. The kiosk can break a large euro note into lei, then use the lei to pay for the SIM. That way you avoid carrying excess cash. The whole transaction takes less than ten minutes and leaves you with local currency and connectivity for under €15.

Drinking Water: The Bottled Reality

Tap water in Bucharest is generally considered safe by locals, though some visitors prefer bottled water due to taste or sediment. The city's water treatment meets EU standards, and many locals drink it. But outside Bucharest—in the countryside, the Danube Delta, or smaller towns—the tap water may contain sediment or bacteria. Bottled water is the norm. A 1.5-liter bottle costs 1–2 lei at any kiosk. At the airport convenience store, the same bottle is 8 lei. The markup is not just at the airport. Hotel minibars charge 5–7 lei for a small bottle. The smart move is to buy a 5-liter jug from a supermarket (about 4 lei) and refill a reusable bottle. Some subway stations have free refill stations—look for a water fountain near the ticket hall. At Piata Unirii, there is a self-service refill point for 0.5 lei per liter. Carrying a reusable bottle is practical in Bucharest, where the climate is continental—hot summers, cold winters. Dehydration is a real risk, and buying single-use plastic bottles adds up. The kiosk sells both still and sparkling water, usually at the same price. Check the label: "plată" is still, "minerală" is sparkling. One more trick: if you are hiking in the Carpathians, do not drink from streams without purification. Giardia is a risk. Pack purification tablets or a filter. The kiosk in the train station at Brasov sells tablets for about 5 lei. Again, the mundane infrastructure—the kiosk—solves a problem that glossy travel features ignore.

The Bag Drop Loophole Most Miss

You have a few hours between check-out and your train. You do not want to drag a suitcase over Bucharest's cobblestones. The solution: left-luggage at Gara de Nord, the main train station. The official luggage storage charges 10 lei per bag per day. The airport storage charges 30–40 lei. The difference is stark, and the train station is on the metro line. Some hotels will hold your bags for free even after check-out. Ask at reception. If they say no, the Gara de Nord storage is a five-minute walk from the metro exit. It is secure, staffed, and open from 6 a.m. to 10 p.m. You can also find lockers at select metro stations—Universitate has a row of lockers for 5 lei per hour, but they are small, suitable for a daypack. Plan ahead. If you are taking a train from Bucharest to Brasov or Sibiu, dropping your bag at Gara de Nord saves you a trip back to the hotel. The same logic applies to the airport: if you have a late flight, store your bag at the train station, explore the city, then take the express bus to the airport. The bus costs 3 lei and runs every 20 minutes. The bag drop is a small detail, but it changes how you experience the city. Without a suitcase, you can walk through the Old Town, visit a museum, or sit at a cafe without the weight. The math is simple: 10 lei versus 30 lei, and a hassle-free afternoon. The subway kiosk, the train station storage, the water refill—these are the unsung heroes of a well-planned trip to Romania.

When the Kiosk Isn't the Best Option

As reliable as the subway kiosk is, it is not always the best choice. If you arrive late at night and the kiosk is closed, you have no choice but to use the airport ATM or exchange bureau. In that case, withdraw only a small amount—enough for a taxi or bus fare—and exchange the rest the next morning at a kiosk. Another scenario: if you are exchanging a large sum—say, over €1,000—a bank might offer a better rate than the kiosk, which has a €500 limit per transaction. Banks like BCR or BRD can handle larger amounts with a rate close to the interbank rate, but you will need to go during business hours and may pay a commission. For most travelers, though, the kiosk wins on convenience and rate. Also, if you are heading directly to another city like Brasov or Sibiu from the airport, you might not pass through a metro station. In that case, exchange at a bank in the city center after you arrive, or use an ATM. The kiosk is best for those starting their trip in Bucharest. Finally, if you prefer the safety of a bank over a convenience store, that is a personal choice—but know that the kiosk is regulated and widely used by locals. It is not a sketchy operation; it is a standard part of daily life.

None of this is revolutionary. It is the kind of practical knowledge that accumulates over repeated visits. Romania is a welcoming country with rich history and affordable prices. But the conventional travel coverage, with its focus on Bran Castle and the painted monasteries, skips the everyday math that saves you money and frustration. So, what will you do differently on your next trip to Bucharest? Skip the airport bureau, walk to the metro, find the kiosk, and start your trip with a better rate. Or will you stick with the ATM and pay the premium? The choice is yours, but the math is clear.
