This place is really great ! the appartment is comfy, quiet. There is a big terrace with a nice view. It's close to the metro which bring you to the center of Athens in less than 15 mn. A little map above the desk shows you usefull points near the place like the closest supermarkets, ATM or metro station.
Stavros and Katerina are really nice and avaliable people (they live in the same building)
The flat is perfect for a little trip to Athens alone or in couple
