This flat is on two floors and has fantastic views of the Acropolis and city. The outside balcony space is large and the whole place is very spacious and clean.
There were five of us and the fifth bed is actually just a sofa in the living room. It was large and comfortable so not a problem, but it might be useful for other travellers to know. Communication was extremely prompt and the hosts were always helpful.
I would definitely recommend this flat and would happily return again.
