The apartment is in a fantastic location. On the same metro line as the airport and a minutes walk from Kerameikos square with its bars and restaurants. We walked everywhere, but the central metro stations are all a 4 or 5 minutes/1 or 2 stops on the metro.
The building itself is modern and well maintained. The apartment is spacious, comfortable, modern and beautifully designed with stunning views of the acropolis from the hot tub on the roof!
I couldnt recommend staying with Kostas & Dimitris enough. Incredibly helpful, informative and accommodating.
