The flat is very beautiful, spacious, with two bathrooms and two bedrooms, is ideals for two couples or family! The neighborhood have all the necessary for living there ( market, bars, bakery, etc) and for funny (two disco-pub near). Also, it's relative close to two underground station (Acropolis and Aghios Ioannis) and taxi stop. The host also give more information about the place to visit or where to eat, through AirB&B or whatsapp.
I highly reccomended the flat, if I will return to Athens, i will hope to return here!
