We had a great stay in Nassos's place - the location was great, it didn't have all the loud hustle and bustle of places closer to Athens and felt much more local. Very close to the Petralona metro station, and also really close to Piraeus if you want to do a day trip to an island - totally doable! The water heater was kind of irritating as it took over an hour of continually pressing the button to have enough hot water for a 20 min shower, but it was a small price to pay. Everything was exactly as expected and Nassos was very helpful through his communication. Definitely recommend to anyone looking to stay in Athens!
