Hilton San Francisco Union Square

Hilton San Francisco Union Square is the largest hotel on the West Coast, purpose-built to welcome the world through scale, service, and a commanding sense of place. With 1,921 guestrooms spanning three towers, this property delivers capacity without compromise—offering the inventory to accommodate citywide conventions, the flexibility for landmark celebrations, and the consistency for business travel at every level. Scale is an asset here. The hotel offers over 130,000 square feet of meeting and event space, making it a premier stage for gatherings of any size or complexity. From the soaring ceilings of the Grand Ballroom to the light-filled Yosemite Room, every event is supported by our 24-hour on-site event planners and technical talent who handle the details while you command the room. The experience extends beyond the meeting agenda. The 46th floor is home to Cityscape Sky Bar—San Francisco's highest sky bar—offering 360-degree views of the Bay and the city skyline. Guests can also take a dip in the heated outdoor pool and hot tub, or stay on track in the 24-hour fitness center. For dining, the property features Poached Breakfast Restaurant, the Lobby Bar, and Herb N' Kitchen for a quick, quality bite on the go. The location puts guests at the intersection of it all, just steps from Union Square, the Powell Street cable car turnaround, and a short distance from the Moscone Convention Center and the Theater District. With easy access via BART and MUNI, Hilton San Francisco Union Square serves as the definitive base for those looking to command their stay in the city.
