Hilton San Francisco Union Square

Commanding an entire city block in the absolute heart of the city, the Hilton San Francisco Union Square is an energetic, expansive, and iconic destination. As the largest hotel on the West Coast, this 1,921-room property is a city within itself, offering a comprehensive and dynamic experience for business, convention, and group travelers. Its three towers rise dramatically over the city, placing guests just steps from the world-class shopping of Union Square, the acclaimed productions of the Theater District, and the vital pulse of the Moscone Convention Center.

The hotel’s history is woven into the city’s architectural story. The original 1964 building was a marvel of its time, a pioneering example of Brutalist design with a unique “motel within a hotel” concept, featuring ramps that allowed guests to park directly near their rooms. This innovative spirit continued with the addition of the soaring 46-story main tower in 1971, which forever shaped the San Francisco skyline. Today, this legacy translates into a property of impressive scale, capable of hosting the world’s most significant conferences while providing personal comfort to every guest.

Accommodations are thoughtfully designed to provide a restful retreat from the city’s buzz. The 1,921 rooms and suites are divided among the three towers, each offering modern amenities and a clean, contemporary design. Options range from spacious King and Two Double Bed rooms to expansive Junior Suites and One-Bedroom Suites, many of which feature private balconies. For an upgraded experience, the Skyline View rooms on floors 20 through 44 provide breathtaking panoramas of the city skyline, the Golden Gate Bridge, and the Bay. Every room features a large flat-screen TV, a comfortable work desk, and premium bedding.

The hotel’s amenities are as grand as its scale. A rare and celebrated feature is the 16th-floor outdoor pool deck. This expansive oasis features a large heated swimming pool and a relaxing whirlpool, all surrounded by comfortable loungers and protected from the wind, creating a resort-like feel in the middle of downtown. A 2,800-square-foot, 24-hour fitness center is fully equipped with a wide array of modern cardio and strength-training machines.

Dining and entertainment are highlighted by one of the most spectacular venues in San Francisco. Cityscape, the hotel’s 46th-floor sky bar, is the highest in the city and offers staggering 360-degree views. From this vantage point, the entire Bay Area unfolds at your feet, from the Golden Gate to the Bay Bridge and beyond. The lounge, recently redesigned to feature restored mid-century modern artwork, serves a creative “Cocktails of the Cosmos” menu, making it the ultimate location for a sunset toast or a dazzling nightcap. For more casual needs, the hotel provides a range of options. Poached is the hotel’s dedicated breakfast restaurant, serving a full and varied buffet to start the day. For quick bites, Herb N’ Kitchen is a 24-hour grab-and-go market offering artisan sandwiches, fresh pastries, coffee, and even room delivery.

As a premier conference hotel, the property boasts over 130,000 square feet of flexible meeting and event space. This includes the massive 30,000-square-foot Grand Ballroom and the elegant Continental Ballroom, both capable of hosting major trade shows, galas, and conventions. A dedicated Executive Conference Center and dozens of breakout rooms provide endless configurations for groups of any size, all supported by a world-class events team.
