Rena is a very great host, we were arrived at morning, and the check in time is flexible! Around 100+ steps down to the cave house from main street, Rena's staff took our 2 big luggages down the stairs! The view is awesome, we spent a lot of times with that incredible view and played with Rena's cats and dogs, the place is quiet, and private! I'd like to recommend Rena's cave house to you all. And of course, I'm going to stay again when i back to Oia next time!
