A polished Union Square hotel with spacious rooms, an indoor pool, and excellent service at reasonable prices for San Francisco. The lobby features an impressive koi pond and Japanese aesthetic. Central location makes exploring the city easy.
Hotel Nikko San Francisco stands at 222 Mason Street in the Union Square district, one block from the Powell Street cable car turnaround and within easy walking distance of Union Square's shopping, the Theater District, and the Financial District. The hotel occupies a 25-story tower and is one of the larger full-service properties in central San Francisco, with 533 rooms and suites. Originally developed with a Japanese aesthetic that continues to distinguish it, the lobby features a decorative koi pond and clean architectural lines referencing the hotel's Nikko heritage. Guestrooms are notably spacious by San Francisco standards and furnished in a contemporary style with warm wood accents and muted tones. Upper-floor rooms offer city views in multiple directions; some face toward Twin Peaks and San Francisco's western neighborhoods. The indoor, heated swimming pool on an upper floor is a practical amenity given San Francisco's frequently overcast and cool climate—a rare feature among Union Square hotels. An adjoining fitness center is also available. ANZU Restaurant on the ground floor serves California-influenced cuisine with a respected bar program, drawing both hotel guests and neighborhood diners. A dedicated business center and meeting facilities serve the hotel's considerable corporate clientele, which benefits from easy access to the Moscone Convention Center and the Financial District. The Union Square location provides excellent public transit access: BART and Muni Metro stops at Powell Street are a short walk, and the cable car system connects to Fisherman's Wharf and Nob Hill. San Francisco International Airport can be reached via BART in approximately 30 minutes. At pricing typically $180–$320 per night, Hotel Nikko offers a credible mid-range position for a central, full-amenity property in one of America's most expensive hotel markets.
