Kostas's apartment was the last stop on our week long trip throughout Greece, and we're pretty glad it was. It was our favorite apartment by far. We did not have the pleasure of meeting Kostas but his communication through Air B n B was quick and easy, and a gentleman named Alex greeted us and helped us get into the apartment as well as advice on places to go throughout the city and how to get there. The apartment was very clean, and nothing super special about the decorations but it was well done, very modern, and very homey. 5 adults hit into the apartment comfortably, and the AC was a huge help in the Athens heat. I would strongly recommend booking and will let all my friends know to stay here if they were to visit Athens.
