Otium Villa (Bluedome Cavehouse Villa) is amazing. The pictures do not do it justice as the views are breathtaking -- the view is literally the one on all the postcards and you can sit in your private hot tub while you enjoy it. The fact that it is an authentic converted cave does not take away from the upscale feel and was a bonus as it was exciting for our kids to stay in a real cave. Nick provides every amenity you can think of including breakfast items, a welcome bottle of wine and a basket of fresh fruit. He has thought of everything and was readily available during our entire stay for anything else we needed -- from ordering take-out to arranging transportation to restaurant advice to arranging a sunset sailboat tour of the caldera. He is a true local and completely knowledgable about and well connected in Santorini and Oia. There are quite a number of steps to reach this villa, but do not fear...he arranges for people to help carry your luggage.
