Staying at Rena's house in Oia was easily the best part of our trip. The place is a wonderful cave house with a comfortable bed and a spacious bathroom. But the thing which makes this house the best in Oia is the view. From the balcony one can see the caldera in all its majesty. Rena was also kind enough to arrange for our transfer from the airport. She gave us some wonderful restaurant recommendations and we had a lot of fun exploring Oia by ourselves.
