We stayed 3 nights and 4 days in this apartment and I have positive as well as negatives things to say about it:
Positive - very close to the center, my favorite side of Athens, close to metro, close to food,bars, coffees, supermarkets, big apartment, nice balcony, good bed sizes, you can reach them to every daytime, we were allowed to stay longer than the normal checkt out time because there was no one coming after us.
Negative - Very dirty, bathroom, bed and towels were full of hair, broken toilet, just one (half) roll toilet paper (I stayed in some air bnb apartments and this has never happened to me), the guy who was doing the check out was very unfriendly and in a bad mood because somebody hasn’t told him that we were allowed to check out later. The biggest thing for us was the leak of cleanliness that was not nice even for 3 days, every thing else was just a small negative thing.
