If you plan coming to Oia, this is THE experience: renting a cave house with jacuzzi and a superb view. The house is all white with minimal details and design and I loved it. The jacuzzi and view is what you are actually paying for and it is totally worth it. The jacuzzi is heated and you can stay all nigh if you want. The house tends to become humid, but they have installed a dehumidifier. Choose carefully the dates as the prices differs.
