The Hotel Union Square has achieved that rare hat trick of history, location, and style. It's San Francisco's first boutique hotel, built in 1913 for the 1915 Pan Pacific Exposition, and it's only a half-block from Union Square, in the heart of the city with the cable cars passing by your window. Its 2008 renovation has juxtaposed contemporary and classic San Francisco with original 1915 Egyptian mosaic murals and opulent moldings contrasted by sleek furnishings and state-of-the-art technology. The guest rooms are like urban apartments, each outfitted with platform beds with custom-made leather headboards, velvety chaise longues, and flatscreen televisions. Many have an open, loftlike layout with exposed brick walls and floating ceiling installations, while the two rooftop penthouses are the ultimate in chic, with expansive redwood decks with city views. There's also a custom Kids Suite, a Dashiell Hammett-themed suite, and "Sleep and Soak" rooms on each floor that feature spalike bathrooms.
