We stayed at Kiki's place for a week and had a wonderful time!
The appartment itself is fantastic and has many small clever details that made our stay super nice - like the balcony or the bedroom that can be opened into the main living space. It is also clearly a place where the owners normally live, which makes it so much nicer than many Airbnb flats. The location is great, close to nice restaurants, metro and a short walk from the Acropolis.
Kiki welcomed us in person and was very thoughtful (she even left us some food for my small child and offered to lend us a buggy)! She also gave us plenty of great local tips (many of which we followed).
Overall, this is a great spot and we'd be very happy to come again!
