I recently stayed here for an entire month. Having stayed in my fair share of Airbnbs, this one was my favorite. The layout is contemporary but very practical. This place was immaculately clean with a great shower. The water pressure was strong, very hot, and plentiful (for those of you that give this importance).
For me, the best part of this place is its location. It's just outside the tourist realm which is ideal. I could easily walk anywhere of interest but come back to a quiet neighborhood. I always felt safe there, too. Very safe. And there is a family-run restaurant 30 seconds away from the entrance that has outstanding Greek food.
If you are looking to experience the Athens culture (not just the Acropolis), then this is the place for you. After staying there for a month and going all over Athens, I truly think this may be the best location that someone can stay when visiting this energetic city.
