Only good things to say about this place and the host, Romanos. We had a small problem with the bathroom doorknob and it was repaired immediately.
The location was great, everything is within a fifteen-minute walk, including the Acropolis and the major squares, many are much closer than that. Infinite restaurants open late right near the apartment, delicious foods of all kinds. Grocery just down the street.
The room is spacious and has two nice bedrooms. Shower has lots of hot water. Entry is easy with card.
I highly recommend this place if you're staying in Athens.
