Great location. Smooth communication with the hosts who were very nice. The rooftop terrace has a fantastic view of the Acropolis and the city, but it's in another building. The flat was clean with air-condition, but quite old and not everything is in the best shape. I learned that it was normal for Athens, especially in this part of the city.
I actually don't mind spending more to get better conditions. There was a discrepancy between my expectation and what I got, but it's also partly my fault for not having done more research on the living conditions in Athens. This is an excellent choice if you're on a budget. The hosts made great efforts with what they have and for that I'm grateful.
