Expansive walls of glass define Residence , a substantial three-bedroom, three-bath corner home at the St. Regis Residences. Across approximately 2,027 square feet, Downtown architecture, Salesforce Park, the Bay Bridge and the surrounding skyline become an ever-changing backdrop to the interiors.

A defined entrance opens to a gallery-style foyer hall before arriving at the open living and dining spaces. The living room has east-facing views, while the dining area enjoys both north and east exposures. The Poggenpohl kitchen, appointed with top-tier appliances, connects to the main living spaces from two directions, creating a highly functional layout for both daily life and entertaining.

The primary suite is generously proportioned, with a generous walk-in closet and marble bath featuring dual vanities, a soaking tub and separate walk-in shower.

From the 37th floor of the Four Seasons Hotel & Residences, captures sweeping south and west views across San Francisco. The Bay, Twin Peaks, Sutro Tower, and the hills above Market Street create an expansive panorama that shifts throughout the day, with a western orientation offering sunset views year-round. Spanning approximately 1,855 square feet, the Residence begins with a gracious entrance gallery creating a sense of arrival before joining with light-filled living spaces finished with dark herringbone-patterned hardwood floors. Generous living and dining areas offer flexible spaces for entertaining and everyday life, while the kitchen features granite countertops, a w**e refrigerator, and appliances by Viking, Miele, and Sub-Zero. The bedroom wing provides privacy from the main living spaces, with both bedrooms offering en-suite baths. The spacious primary suite includes a bathroom with dual sinks, soaking tub, and large, walk-in shower. A powder room and dedicated laundry complete the residence. What distinguishes life at Four Seasons is not simply the address, but the ease that comes with it. A dedicated concierge is there when needed, while valet parking makes arriving home effortless. In-room dining can arrive at your door 24 hours a day. Housekeeping and engineering assistance are available on demand. And when you leave—whether for a weekend or several weeks—you simply close the door behind you, knowing everything at home is in capable hands. Residence 37G combines the privacy of a home with a level of branded hospitality few residential buildings can offer: effortless, discreet, and unmistakably Four Seasons.
