The arctic-blue glass exterior and subdued, Zen-like lobby may be as bland as an airport concourse, but they're merely a prelude to the spectacularly light, expansive, thoughtfully laid-out guest rooms, which have all the ultramodern conveniences. The hotel lies within shouting distance of Moscone Center, so its business is geared toward convention and corporate travelers, which, depending on occupancy, can make for lower rates on weekends. Bar 888 specializes in vintage grappas, and the award-winning Luce Restaurant, trimmed in iridescent black mosaic, serves modern Californian cuisine. The quiet Club Lounge offers hot breakfasts, tasty snacks, sandwiches, beverages, and desserts, plus access to computer terminals and a pleasant outdoor terrace. The spa provides an array of treatments ranging from massage to botanical facials. Hotel guests have access to the pool, whirlpool, and steam rooms.
