Great apartment in a good area of Athens. We booked for 3 nights but felt so comfy that we stayed for a week. The district (Mets) is nice with fine restaurants and bars and close to a metro station. You can also walk to the City Centre (half hour).
The apartment has a balcony in front, at the back and on top. That way we couldn't miss the december sun before we moved north again to face the cold.
