The view and location of this spot are 5 star. A short walk to Plaka, the Acropolis, the metro.. Very centrally located! Also, nice and spacious flat for 2 people.
My only comment would be that if you're traveling with a lot of bags or if you're older, this may not be the place for you to stay. You walk up 5 floors of stairs because there is no elevator. This was a bit troublesome with our baggage but would be my only negative comment.
