Konstantinos was a great host. Responsive, helpful and friendly. The apartment was large, comfortable, and well-appointed. We fell in love with the Exarchia neighborhood, which was lively, interesting and filled with delicious, inexpensive restaurants, and was also relatively convenient to the rest of the city. Konstantinos was very helpful in arranging transfers to and from the airport. The large wall map of the neighborhood, with recommendations, was very helpful in getting oriented to the area. We highly recommend it.
