We stayed at this penthouse for 7 nights. It's located in the heart of Athens. From Athens International Airport you can reach Monastiraki staion about 40 min by train and about 5 min walk from the station to Francis's place. The place was clean, and Francis is very informative, helpful, just a top notch guy. The view is simply AMAZING. Seeing Acropolis day and night worth millions. When I go back to Athen I will def stay in this penthouse.
