San Francisco Mariott Union Square
About San Francisco Mariott Union Square
Standing on the corner of Sutter and Powell streets, our San Francisco Marriott Union Square puts you right where the cable cars climb past our front door—perfect for hopping on and exploring Fisherman's Wharf or North Beach between meetings. We've hosted thousands of corporate gatherings in our 10,000 square feet of meeting space, and our event managers know exactly how to handle everything from board meetings to large conferences. Our Union Square Ballroom accommodates major presentations, while our 30th-floor meeting rooms offer something special—panoramic views of the city and bay that make even budget reviews more inspiring. We provide high-speed internet throughout our spaces, and each room comes equipped with the AV capabilities modern meetings demand. Between sessions, attendees can grab California cuisine at bin480, our ground-floor restaurant and bar, or work out in our 24-hour fitness center. We understand that organizing corporate events can be overwhelming. That's why our sales and event teams handle the details—from selecting the right menu for your working lunch to blocking rooms for out-of-town colleagues. Our 400 guest rooms and 53 suites all feature spacious work desks, both wired and wireless internet, and those plush beds that ensure everyone's sharp for morning presentations. The location works beautifully for business travelers. Moscone Center sits within walking distance, and when you need a break from spreadsheets, Chinatown's just blocks away. Our concierge team knows the city inside out and can point you toward a quiet spot for client dinners or help arrange team outings to AT&T Park. We've learned that successful meetings need more than just four walls and a projector. They need attentive staff who understand business needs, flexible spaces that adapt to your agenda, and a location that makes attendance easy for everyone involved.
