The place is lovely. Good location, 20mins walk to Syntagma square. A bit walk from metro station 20mins, but you can take a bus which stops close to the place. The host is very friendly and nice, he did his best that we would feel like at home :) we enjoyed staying at his appartment. Comfortable bed, not too noisy neighbourhood, nice terrace to have a glass of wine. Place is clean and has all necessary amenities.
The inly thing that he was texting in greek so the translations was not always accurate, so we had some misunderstanding before arrival. It was not a big issue though.
