I totally recommend Konsatantino's place to everyone who is looking to stay in Athens.It is very near to the Monastiraki metro station and there are nice restraunts and bars nearby.I had great time while staying at his place.
Konstantino is a great host, he was personally available for us, though we checked-in late.He is very helpful and kind person. His valuable suggestions and local tips made our Greek experience more exciting and memorable.
