I will reccomend Callia collection to all whom are planning to visit Santorini, specifically the dream cave. It's at an ideal location in Fira, all the action is happening all around you. It's a beautiful room with the most gorgeous view. The attached hot tub is just an added bonus. Christos and Margarita were lost helpful, great communication, and quick responses. Christos checked us into our room, and quickly gave us his direct phone number in case we needed anything during our stay.
