My wife and I stayed at Efi's place for two nights while we were in Athens for part of our vacation. Obviously, the location was perfect and we were pleasantly surprised by how large the accommodations were. It had great wifi and AC and while we didn't use it, it had a large separate kitchen available for us which looked very nice. The metro is right across the street which made it easy to get around and to the airport. We would definitely stay again if we come back to Athens!
