exchanging money at the airport by desert_princess
arrange a price in euros with the taxi driver , some accept such deals, I wouldn't advise you to change money at the airport, they have a very unprofitable rate. In worst case , change a small amount , good to pay the taxi. There is a 24h change bureau at the "Popa". You can ask the driver to take you there so you can change money on the way. it's in the center ,all roads lead to "Popa".. hahahaha
Enjoy my hometown
