Rena's place is breathtaking and exactly what my friends and I wanted- a true cave house experience in Oia. It was within walking distance to all of the main shops/restaurants of Oia, and Rena also had an extremely timely porter on hand to take us anywhere we wanted to go. The walk down and back from swimming and kayaking was ROUGH (It is a steep, rocky climb down a cliff) and we would recommend it only for older children and adults that are in good shape. However, being able to rent kayaks for free and kayak to a cliff jumping spot was one of the highlights of our trip! Rena was so kind and accommodating and her place is truly one of a kind.
