Atm at the airport, also taxis will take sterling( currency not Raheem) dollars or euros. Twenty will get you from airport to town.What are people doing about changing money? Given their currency is almost worthless do they accept euros?
Given the dirt cheap prices ain't gonna need much spends and can't see any exchanges stocking Ukrainian currency and I'm sure they won't be wanting to order it in if it's only a small order say 80 quid
