Great location! The apartment is on a beautiful side street just a minute or two away from the Old Town main square and harbour. We got in pretty late on the first night and were able to easily grab the key from the lock box right by the door. There are tons of great restaurants within walking distance. The host was incredibly helpful and very quick with communication.
Be aware that taxis and buses will not be able to drive into the square, so you will need to walk any luggage over to the apartment (only took us a few minutes so wasn’t too bad). The apartment also consists of three stories with a pretty narrow winding staircase. The first floor has the kitchen, sitting area, and small bathroom; the second floor is the bedroom; the third floor is the patio and full-sized bathroom. Keep this is mind, as we did a lot of walking up and down the stairs. Also, since the main bathroom is all the way up top, it could get quite warm.
Overall the apartment was great for the few days we had to explore Chania, and was in a fantastic location!
