My partner and I chose this apartment for our Christmas vacation in Athens. First and foremost, I'd like to mention the location; it's truly ideal. The apartment is located in a very nice and calm area of Athens, but still close to the centre: the busy shopping areas, the beautiful streets of Plaka and all the popular sightseeing destinations. You can access those either by taking the train (train station is only a 5 minute walk away) or on foot. We'd definitely recommend a walk to/through Filopappou Hill to anyone who stays in this apartment; it's practically next door and a very beautiful place to visit!
Furthermore, the house itself is very beautiful, nicely decorated and cozy. Our main problem was that, since it was winter and quite chilly, we had a hard time keeping the apartment warm at times, but the hosts provided us with some extra options for heating, which helped. The bed was very comfortable, as was the couch.
The hosts were very quick to communicate with us and we very much enjoyed our stay!
