What makes this über-luxury hotel one of my favorites is its perfect combination of elegance, trendiness, and modern luxury. The entrance, either off Market or through a narrow alley off Third Street, is deceptively underwhelming, although it does tip you off to the hotel's overall discreetness. Many of the oversize rooms (starting at 460 sq. ft. and including 46 suites) overlook Yerba Buena Gardens. Not too trendy, not too traditional, they're just right, with custom-made mattresses and pillows, beautiful works of art, and huge luxury marble bathrooms with deep tubs. Adding to the perks are free access to the building's huge Sports Club L.A. (the best hotel gym in the city, with a full-size pool), a 2-block walk to Union Square, and a vibe that combines sophistication with a hipness far more refined than the W or the Clift. Its only contender in that department is the St. Regis.
