If you are going to stay in Santorini, you should do it properly and stay in Oia. And if you are going to stay in Oia, you should do it in a luxurious cave house with stunningly uninterrupted views of the caldera under the care of Katerina.
I cannot recommend Katerina's cave house highly enough, and the care she took of us during our stay made it even more magical. Transfers, recommendations, boat trip and restaurant bookings - she made everything easy. Thank you once again Katerina!
