Only had a slight issue with check in timing and cleaning taking longer than expected. It was difficult to communicate beforehand as there is poor data reception in the area.
The flat is beautiful and clean. The location is perfect for accessing tourist attractions such as Acropolis, Agora etc. It's right behind Acropolis museum.
The hosts respond quickly and are easy to reach. I had no problems during my stay. The instructions for checkout were clearly noted by the door.
