I am very pleased to recommend Sail Inn apartments to anyone wishing to stay in Kamari. It's just a few minutes walk from the bus stop, as well as the beach (the sunrise from the beach is incredible!) There is an agency near the bus stop as well that offers some very affordable tours, especially if your time in Santorini is limited. The room was very clean and spacious. Antonis was extremely helpful and a wonderful guy to chat with. Highly recommended!
