The apartment was absolutely amazing, it really deserves a good review, and the owner was very communicative and helpful with every issue encountered during my stay. Also the place and neighborhood is amazing, Petralona is between Monastiraki - city center and Kallithea which is a very peaceful place with atmosphere. Also the apartment is 2 minutes walk from the metro station which was amazing, supermarket very close. There is really nothing to complain about, the apartment is new and stylish and has everything needed for a short or long stay, but for a longer stay only 1 person because I think it's too small for two people to stay for a long time. But for for example just a week for tourists in Athens - perfect!
