We really enjoyed our stay at George's apartment. It's very comfortable with everything you need from a comfy bed to everything to cook yourself a meal at home in the well-equipped kitchen.
The location is excellent with a grocery store just across the street and several local restaurants nearby. Under 10 minutes walk to two different metro stations Atikki and Aghios Nicholas not to mention the bus basically right on the main road into the city. You can get a 5-day pass at the station which I recommend or buy individual use tickets. I used all of the above at least once during our stay, including the Beat app that is like Uber but for taxis.
Back to the apartment, we would definitely stay here again -- it would be great for a month or more because it's laid out well with good storage so it feels spacious and has good light coming in from the big windows.
This is our second time in Athens staying in this neighborhood and we would highly recommend it if you like to be away from the city center and tourists but have easy access to explore.
George had good communication right from the start online and both he and his family took great care of us during our stay, check in and check out were a breeze. If we had any questions or needed anything they responded quickly.
