FOUND Union Square

Tenderloin, San Francisco

Hop on a cable car and let vacation mode commence. Explore the iconic sights, diverse restaurants, and countless shops that San Francisco has to offer. Just steps away from vibrant Market Street, your cozy space at FOUND Union Square awaits your arrival. You can’t miss this refurbished, black brick exterior with bold golden “FOUND” letters. As you enter the building, you’re met with a mid-century modern lobby coated with subway tile accent walls and herringbone style floors. Step outside and you're faced with the nine-story Westfield San Francisco Centre — where the shopping is endless. Grab a freshly roasted cup on the go from Blue Bottle Coffee. Take a short walk to the lively Union Square plaza. Or escape the city as the fountain sings and the flowers blossom at Yerba Buena Gardens. Discover some of the city’s famous sites like The Painted Ladies or Fisherman’s Wharf. After a day of exploring, the FOUND Union Square is the perfect place to rest your head at night.
