I had a fantastic stay at Giannis's place. He met me at the Metro to walk me to the house, and was very helpful throughout the stay - including printing out ferry timetables, making tea and even messaging me to let me know there was a full moon out! It was in a quiet area, but easy walking distance to the Acropolis, Monastiraki and other fun neighbourhoods. The house itself was spacious, clean and comfortable. Highly recommended!
