We had an amazing time at Kostas' flat! He met us as soon as we arrived at the metro station, which was very conveniently located to the flat. The flat is in a very nice neighborhood, with a bakery, market, and restaurant with delicious souvlaki all right there. The apartment was very clean and comfortable. The terrace overlooking the acropolis was also incredible and we spent a lot of time there! Kostas was extremely helpful and hospitable, providing us with a packet of information and restaurant recommendations, which he marked on a map for us. He also helped us book a cruise to the islands. We would definitely return and I would highly recommend Kostas and his apartment!
