We really enjoyed our stay. The apartment was beautifully lit during the day and the bed was very comfortable.
The location was perfect, the neighborhood is pretty safe and is a very hip and cool place to live in Athens with a lot taverns and coffee shops around. Most important monuments are walking distance from the apartment.
The hosts were very nice and helpful.
I have to note though, that it gets a bit noisy when people walk in the common entrance to the the other apartments.
