its a perfect place to stay if you don't want to be in the middle of touristic craziness.
apartment is new, bright and very clean. it all has a great feeling you are in fancy home. probably it is hard to find that good apartment in Athens - with that style and cleanse.
as flat is not in busy center-center we used to take taxi that is around 5 euro to any part in center, but subway station is very close and its 1 stop from the center.
so I can recommend Vasilis as a great host that will take care about you on all parts of your stay. and he has very nice taste!
