Frequently asked questions
Does Hotel Nikko San Francisco have a pool?
Yes — Hotel Nikko has a heated indoor pool, which is genuinely uncommon for a Union Square hotel. Combined with a fitness center and spa facilities, it's the most amenity-complete option at this price tier in the downtown corridor.
Is Hotel Nikko a good value for Union Square?
Yes — 8.6 guest score across 3,241 reviews, indoor pool, pet-friendly, and a Union Square location at $179. At $100+ less per night than the Westin St. Francis, it's the clearest value pick for families and travelers who want the pool and downtown access without the full-service premium.
What is the neighborhood around Hotel Nikko like?
Hotel Nikko sits on Mason Street just off Union Square — BART and MUNI stations are one block away, the Powell Street cable car line starts within walking distance, and Chinatown is a 5-minute walk. Most Union Square restaurants, shops, and SFMOMA are easily accessible on foot.
How does Hotel Nikko compare to the Westin St. Francis for Union Square?
Hotel Nikko is the value and amenity pick — indoor pool, more reviews, and a rate typically $100+ below the Westin. The Westin is the landmark and full-service pick — Marriott Bonvoy, historic address directly on the square, and the most recognizable hotel name in the neighborhood. For families and value-focused travelers, Nikko; for Bonvoy points and a Union Square landmark stay, Westin.
