Vivi was great! She arranged transport for us to and from the airport, which was very helpful, and the apartment was exactly as pictured. We ran into issues with the wifi, but Vivi was very responsive and sent a technician over quickly to make sure the problem was fixed right away. Overall, the only negative I found with the apartment was its location. Kamari is a great location, especially for those mostly interested in being at the beach all day, but we had just arrived at (if not right before) the beginning of Santorini's open season, so it was a bit too cold for the beach and a lot of restaurants and things were closed in the downtown area. We found ourselves constantly heading to Fira for food and things to do, which we had planned to do knowing we were coming during slow season, but due to the relative infrequency of buses between Kamari and Fira, it was sometimes frustrating and difficult to get from place to place. That being said, this I'm sure will correct itself at least somewhat in Santorini's busy season, during which time I imagine Vivi's apartment is the perfect spot to be!
