We only stayed for one (supposed to be 2 nights but our plane was delayed). George was incredibly hospitable- meeting us at the apartment with his son to help carry our luggage. The apartment is superb - spacious, very clean, smartly designed, and great to stay in. It has nice touches like AC, a balcony and a spanking new bathroom.
What surprised me was the location, which was better than I anticipated. You simply walk out the door. Turn right, walk half a block and there is a promenade with restaurants, a flee market (0.5 km away) and a gorgeous view of the acropolis. Just spectacular.
