Hilton San Francisco Union Square Hotel

About
The city’s iconic host, at the center of it all Hilton San Francisco Union Square is the largest hotel on the West Coast, purpose‑built to welcome the world. From citywide conventions to celebratory gatherings, this is where San Francisco comes together. Guest rooms and private balconies sit higher than any other hotel in the city, framing views that turn arrival into an event. The outdoor heated pool and hot tub are open year‑round. Cityscape Sky Bar—San Francisco’s tallest—offers 360‑degree vistas of the city skyline and the glittering streets below. Step outside and you are at the intersection of Union Square, Chinatown, the Theater District, and the Financial District. Powell Street cable car turnaround is one block away. MUNI and BART connect you to every corner of the city. For our guests, the amenities are anything but an afterthought. Stay on track in the 24‑hour fitness center. Grab a coffee and a quick bite at Herb N’ Kitchen, our 24-hour grab n' go market. Start the morning at Poached breakfast buffet, or rent an e‑bike from G Level and see the city at your own pace. An Avis/Budget rental car desk is also conveniently located inside the hotel. The city is yours. The stay is ours.
