My wife and I had a wonderful stay in Kamari. Vasiliki was a great host; she was available when we had questions/needed recommendations, she was friendly and welcoming and we had no issues with check in/out.
Our room was very clean and quite spacious with our own little walk out. This place is located just a short walk away from the beach and public transportation which was extremely convenient. It's not super close to the really busy/touristy places (Oia and Fira) but the bus allowed us to get to those places quite easily if we wanted to, which I think was the better choice for us as those areas can get really chaotic with tourists.
Overall we had a great stay in Kamari and we would very much consider returning soon!
