Demetris's apartment was just perfect! Taking Metro 3 from the airport to St. Kerameikos station was super easy! A direct line with no stops! From the station it was about 7 min walk. Demetris replied to all my messages instantly and he was very helpful at the checkin. I agree with other comments that the apartment looks even better than on the pictures. The whole building is new and I loved the elevator door opening straight into the apartment. The neighbourhood feels very quiet, even though many clubs and bars are only a few streets away. I can recommend any visitors to stay here!
