Perhaps one shouldn't live in glass houses, but staying in them on vacation can be a real treat. This exquisite villa, with floor to ceiling glass walls all around, is the height of luxury. When you're not gazing at the stellar views, you'll be curled up around the elegant fireplace in a soaring, peaked roof living room that looks like it jumped off the pages of a design museum. The core philosophy here is relax, regenerate, rejuvenate, and there are several sumptuous villas where you can do just that. It’s an experience to relish but it ain't cheap.
