Our stay at the apartment was really nice. The flat was super clean and well-equipped. I was supprised that the flat was cold during the nights, but it was nothing an extra blanket couldn't fix. Also the flat seemed larger on the pictures. The checkin was very easy and quick, just as the checkout. The balcony is probably the greatest feature of the flat. It's large, has sun in the morning until midday and is well equipped.
The location is also nice. It's a ~10 minute walk to the next subway station, and ~10 stations from there to most central places of Athens. Ira placed lot's of guidance in the flat, so we always had good impressions on what to do.
