Our stay of almost 4 days in Athenes at Kosmass' place was really great. The house is located in a superb area and is very well equipped. Metro station at 5 minutes walk, the nicest and authentic restaurants just around the corner and really at the bottom of the hill / parc with great view on the Acropolis. We recommend Kosmass' place to everybody without any doubt, it's a perfect place for your stay in Athenes.
Besides Kosmass and Dimitris have great sense for good and warm hospitality. Compliments.
