I really recommend this place. It is in the perfect center of the city, near restaurants and roof-top bars. And you will not need to take taxi to go out :)
Kostas is very nice host, correct and very helpful. He gave us so good directions to go to the beach.
Also - the place has a spirit and it is very clean and cosy :)
Finally - you can talk with the host on minimum 4 foreign languages.
If we go to Athens, we will go on the same place, for sure!
