John's apartment was great - had a very comfortable bed and sofa, perfectly clean, had all necessary amenities, central (just next to acropolis and the museum, walking distance to anywhere else in central Athens we visited during our visit). The flat is on a pedestrian only street and is very silent. It has a nice balcony to enjoy when it is sunny outside. Self check-in and communication was perfect. I would definitely stay again at John's place while visiting Athens.
