I had a great stay at Giorgos' apartment. It was truly my home away from home for nine days. The apartment was clean, there's a spacious balcony, a beautiful piano and nice flat-screen tv and a comfortable bed, but most of all, Giorgos is a wonderful host. He made sure everything was fine and really cares about his guests.
I definitely recommend staying here and if I'm ever in Athens again, I know where to go!
