The appartment is exactly like It is described, situated in a very calm and safe area, perfect for four people, and equiped with all the amenities that one might need. Yannis is the perfect host, he came and picked us up from the airport and made a quick tour arround the city before we get in the apartment. On our last day he offered us a trip to see other parts of Athens, and that made our trip even better.
I would strongly recommend to stay at Yannis's apartment.
