Kostas's place is in a very good location about a five-minute walk from Larissa metro station, which a few stops away from the Acropolis station and close to grocery stores and a fantastic little bakery. The place was very clean and well kept with a large balcony that has a view of the Acropolis. Kostas was a great host and provided us with lots of tips for restaurants and things to do while we were in Athens. I highly recommend this place!
