We loved the apartment. It's even better than in the pictures - large, spacious, high ceilings, and right in the heart of everything. Restaurants downstairs do mean that there is some noise at night, especially on the weekends, but this is to be expected given the location. It really is in the heart of central Athens so really easy walk to so many places, including the Acropolis. The view from the roof is amazing!! George was very responsive and helped us to arrange a transport from and to the airport. Would highly recommend!
Quick note that there are stairs from the front door of the building to the apartment and then even within the apartment, so if anyone in the group has mobility issues, this would not be the place.
