Highly recommend staying at George's place! Very modern, very clean, very welcoming. Very close to the city center, to the Acropolis, and to the metro station. Although there is lots to do around the neighborhood at night, George's place is conveniently located (close to everything) and quiet to get a good night's sleep. George replies back right away, is very flexible with check-in times, and will even come to greet you at check-out if you're lucky :)
