The apartment is located in the heart of Athens with many bars, restaurants and sightseeing attractions around. The check-in went well and the price was ok.
However, if cleanliness is important to you, I can NOT recommend it. The room was obviously not cleaned when we arrived (there was shit sticking in the toilet, many hair lying on the floor and the trash bins were full). Furthermore, there was no toilet paper in the room, which just sucked after arriving from a long travel day.
I hope, that Konstantinos will pay more attention to preparing a clean and comfortable room for future guests. For us, it was a No-Go apartment.
