Rena's place is in a very unique spot. Great location because you're removed from the bustle of Oia's cobblestone streets and you're literally the last row of caves overlooking the Caldera. Challenging location due to the steep steps required to get to/from the cave houses. There is an alternative path that makes the climb up and down a bit easier. You do make decisions about lunch and dinner based on how many times you want to go up and down. The caves are very old, furnished "traditional" (mismatched, basic) and honestly feels a bit like "glamping." They could benefit from a deep cleaning and tossing out some outdated/useless items. Rena, Matel and Nicolette were amazing, carrying our bags, arranging for transportation, dinner reservations and helping with a medical emergency. We loved sitting out under the stars and enjoying a glass of wine. The animals are cute (numerous cats and dogs), but they are used to hanging around and coming into the cave houses, so if you have allergies, be aware and keep the doors closed!
