The apartment is a studio located in an excellent area of Athens. It is right between the National Gardens and Plaka and it was very easy for us to explore the city from here (the Acropolis, Plaka, Monastiraki, Exarcheia, Likavitou, etc). The apartment was clean and we felt comfortable during our stay here.
One of the great things about having Sean as your host is that he was excellent with communication. He also spent a considerable amount of time introducing us to all of the great places to visit in Athens--the insider tips were really helpful. I recommend staying here!
