Vasia's and George's place was easily one of the best apartments I've ever stayed in. It was spacious, full of light, extremely clean and simply gorgeous in all regards. The neighborhood was also really lively, full of pubs, restaurants and coffee places, with people walking around all hours of the day. The location was also superb, as the Subway was only a 3-minute walk, and then only a 5-minute ride to the city center.
Vasia and George were also very hospitable, helpful, and quick to respond to any questions. If you're visiting Athens, you'd be hard-pressed to find a better apartment to stay in. 5/5
