We were four adults and stayed there for two nights. The apartment was very well located, right in the vicinity of Acropolis (2 mins walk) and it was just opposite to a very famous bakery. The apartment has all the necessary facilities including washing m/c. I had a very nice stay at her place and I like to recommend this place to anyone who would like to explore central Athens by foot.
Roula was a kind host, as she greeted us with cherries, strawberries and cookies. She also gave us plenty of touristic information.
