Christos is really a very nice and helpful host. He gave me a map of Athens and he helped me with anything i needed. His house is truly very centrally located only one metro stop from Monastiraki and Acropolis but anyway you can walk it also, because on the way from his house to Monastiraki you pass the ancient Romaic market, which is a pedestrian and very nice road. Under his house there a lot of coffees, bars and restaurants with good prices and good quality of food. The view from the room and balcony was really amazing, so i spent a lot of time enjoying Acropolis, Lecabettus and Gazi square. His area has a lot of people , so it is very safe to walk even in the night. The house has everything you need (hairdryer,iron,clean sheets and towels etc.). The most important is you take only one metro from airport and on the exit you see the house, so it is very important for someone with luggages.
