The place we stayed in was lovely and situated in an ideal location, making most landmarks close by easily accessible by either walking or by the metro. We loved that we were seconds away from a small, stylish bar with very nice outdoor seating and quick service.
The place is ideal for couples who are staying over for a few days as it has everything you need to stay comfortable and happy. I especially liked the aircon as Athens is incredibly hot this year.
Unfortunately, the hot water from the shower stopped working after the first night, but that wasn’t too big an issue as it was nice to cool off from walking around in the heat. Also, I would have personally liked it if there were some more pots and pans (and a multi-stove!) so that I could have been a bit more explorative with cooking.
Other than the above, I would highly recommend staying in George’s Airbnb if you are sightseeing around Athens - it’s ideal!
