Kiki was very kind and the communication with her was really easy. The appartment is super nice and the terrace is the best part of the appartment! It has a beautiful view to the akropolis.
Arround the corner it has a small supermarket.
You can easily walk to the centre of athen (monastirakis, exarchia..) and the next metro-station (Metaxourgio) is 5 minutes by foot.
The only problem was that the toilet did not work properly but it was okay.
