Hi - I've just reserved a room in Greece and the room owner has asked me to pay a deposit via SWIFT and has sent me her bank details. As I usually, just turn up on an island and find a room, this is all new to me (I suppose the 21st century had to hit Greece at some point!

) - anyone ever used SWIFT to pay a deposit abroad? How did you do it and how much did it cost??? I'm looking at 100 euro deposit.
Thanks in advance
