We LOVED staying at Konstantino's place. The location was absolutely perfect, especially for it being our first time in Athens. We were able to walk everywhere and as two single women traveling together we felt perfectly safe not only in the apartment but also walking to and from all the areas we wanted to visit like the Plaka, Monastiraki, the Acropolis...etc. Nothing was more than about a 20ish minute walk. Konstantino had nearly immediate responses to any questions we had and even sent someone over immediately to teach us Americans how to use a Greek washing machine. The kitchen was stocked with all kinds of food for us and the place was spotless. Couldn't recommend this property more!
