Looking to mingle with San Francisco’s game changers? Book a suite at the Battery. In 2014, entrepreneurs Xochi and Michael Birch opened this private, members-only social club in San Francisco’s Jackson Square neighborhood (also known to history buffs as the Barbary Coast). Nonmembers—and travelers—can gain access to the entirety of the club by staying in one of the Battery’s 14 hotel suites or the penthouse (with its own private roof terrace). Designer Ken Fulk created opulent, stylish spaces throughout the interior—think lacquer paint, Chesterfield sofas, and a rotating collection of art, with a focus on portraiture. The Battery houses several cocktail bars, including one with a secret passageway into a small speakeasy; a restaurant that can accommodate groups; a gym; a coffee counter; and a library (each club member selects a book when admitted). The guest suites are large and modern by San Francisco standards, with amenities including Geneva sound systems and Malin + Goetz bath products, plus locally sourced liquors and snacks for late-night cravings.
