My experinces at in Fotis apartment are pretty good. The apartment has a great location. It is litterally at the heart of the town. And the apartment almost the same with the pictures. It is clean and safe. You can walk everywhere so easyly. The only problem about the apartment is mosquitos. I had really hard time to sleep because of them.
I can highly recommend this apartment but you should take something with you to rescue yourself from the mosquitos attack. I guess if i ever visit Athens i'd like to stay there. But for sure that i have to take some prevention for mosquitos.
