We had a wonderful time in Rena's cave house! It is very authentic and a great spot if you want to stay in Oia but be away from the hussle and bussle, as it is on the bottom level of dwellings on the side of the cliff. Many friendly cats and dogs. We are happy that we followed Rena's recommendation for traveling from the port to Oia - the transfer company was very professional and took us right to Rena's porter. The kayaks and swimming near Amoudi Bay were the highlights! Many great restaurants around Oia (Roka, Kyprida) but our favorite was Pitagyro- really just the best for price, flavor, authenticity. Right by Drossos transportation. Thanks for a great time Rena!
