Nasos is really a great host. We were arriving to Athens at an unknown hour from Delfos and he made it really easy for us to meet him. He was available at all times and replied quickly all our messages. The apartment is great. Fantastic location near the New Acropolis Museum, Plaka, Monastiraki and all the interesting sites. It's a very safe area and has shops around to buy food or anything you need. He also explained were to go, were to eat at good prices, shop, etc. We felt really comfortable here and recommend to everyone who is interested in visiting Athens to stay here. The apartment was also very clean.
