Excellent place. Very clean, functional and cozy. The location is as good as it gets for Athens sightseeing. The hosts were helpful and quick to respond. There is a mini marker and grocery store on the same street which was very convenient for my 8-day stay. I highly recommend this place.
A couple of notes to keep in mind: The building has no elevator and the apartment is 2 floors up. Also the wifi was unreliable during my stay, but the surges due to the pandemic might partly be to blame.
