About Hilton San Francisco Union Square

An oversized tower property on O'Farrell Street, the Hilton Union Square rises across 46 floors making it one of San Francisco's largest hotels, with Union Square's retail grid one block east and the Tenderloin boundary immediately west.

Rooms include refrigerators, laptop safes, and flat-screen TVs; an outdoor pool and hot tub occupy an upper deck with bay views on clear days. The fitness center, bar, coffee house, and on-site restaurant handle most guest needs without leaving the building.

The Powell Street BART and Muni station sits a three-minute walk away, connecting directly to SFO in roughly 30 minutes. Check-in opens at 15:00; the tour desk can arrange Alcatraz tickets and wine country day trips.
