Nestled in the Huntington Hotel of San Francisco, you'll find Nob Hill Spa sprawled over 11,000 square feet. The decor has global influences—Victorian, Italian, Chinese and Japanese. There are ten treatment rooms where you are assured to get pampered and spoilt—choose a room with a fireplace during the winter months. There is also a pool and a jacuzzi, but a word of caution—no children are allowed! Apart from the usual saunas and massages, you can also avail of weight training classes and the Pilates-expert. There is also tai-chi and yoga on offer. After all the pampering your appetite might just get the better of you, so make sure you order something from room service.
