A “well-kept secret” sounds cliché, but The Battery in historic Jackson Square certainly qualifies as a private club. This invitation-only membership club is sought after by San Franciscans and has just 14 spacious suites decorated by Ken Fulk. The accommodation has exposed brick walls, period features, vintage furnishings, and original artwork. Courtyard rooms overlook the club’s garden, others have knock out views of the Transamerica Pyramid landmark. Best of all, resident membership is bestowed upon hotel guests for the duration of their stay.
