The appartment was very clean and comfortable, everything was perfect. We only had a little problem with the automatic check-in, but the host was very nice and he immediately helped us getting into the room. The kitchen and the bathroom were very clean as well and the location of the appartment was only 1km from the Acropolis metro station so it was really nice for exploring the city!
We would totally recommend this host and this room if you are to sleep in Athens!
