Athina herself is a great host and quick with communication. The apartment itself is lovely and decorated tastefully. Extra blankets could be found in the closet and towels were provided. Athina also leaves candy, cookies, and water for guests which is a nice touch.
The only thing I would advise to guests arriving late like I did is that the building itself doesn’t have a lobby light. So if you arrive past sunset, I recommend having your flashlight on your phone ready to navigate the grounds. However this was a minor thing for me and would book this place again if/when I come back to Athens.
