A Boutique hotel in Downtown San Francisco California

The Hotel Adagio is proud to offer 171 of the largest, most comfortable and stylish guestrooms of all hotels in downtown San Francisco.

Bridging the gap between classic and new, historic and contemporary, and style and comfort, Hotel Adagio is unlike any Union Square hotels in San Francisco. Our sleek, modern design and cutting edge technology imbues over 4,700 square feet of meeting and event space. Our distinctly unique meeting and event spaces are customizable and will conform to your needs, whether they are big, small or somewhere in between.
