Hotel Union Square

Hotel Union Square is located at 114 Powell Street in San Francisco, California.

It was built in 1908, had a speakeasy in the basement during the Prohibition Era, and Dashiell Hammett was a patron.

[1] During the Prohibition Era, a 10,000 square feet (930 m2) speakeasy called The Golden Bubble was located below the hotel.

In 1935, Egyptian-style mosaics by Helen Bell Bruton were added in the entryway.

Dashiell Hammett and Lillian Hellman may have conducted much of their love affair at the hotel,[6] and he booked his bride-to-be Josephine Dolan into a suite there on the night before their 1921 wedding.
