The location is great, the apartment was clean, the futon—despite being a futon—was quite comfortable, and the shower and bathroom appear to have been recently renovated. I also felt quite safe with the locking system (one lock for the front door, and a second, different lock for your bedroom).
However I received some conflicting information from the hosts about how to get into the building that made checking in late at night a bit stressful. I also felt a bit unsafe using the staircase you need to access the room. It is quite dark (there are lights in some areas but they are timed to go out after a short period), has broken windows, broken mirrors on the ground and seemed like it could’ve been cleaned. The room also smelt a bit... off, at times, like sewage, but that may be a common issue in central Athens, I don’t know.
Overall, if you’re skittish like me and want to feel super secure in a building, this might not be the place for you. But if you’re not and you just want something super minimalistic in a great location in Athens this will probably be a good fit.
