The St. Regis Residences pairs the privacy of home with the service and amenities of one of San Francisco’s premier hotels. This expansive two-bedroom, two-and-a-half-bath corner residence offers the building’s largest two-bedroom floor plan, approximately 1,792 sq.ft., along with a private terrace overlooking the city. Floor-to-ceiling glass surrounds the living and dining areas, with sweeping views across the San Francisco skyline, Twin Peaks and Yerba Buena Park.

Dark hardwood floors run throughout the principal living spaces. The glass-walled kitchen features Poggenpohl cabinetry, high-end appliances and clean contemporary finishes, maintaining a visual connection to the surrounding views. Directly off the living area, the private terrace provides rare outdoor space for dining, entertaining or simply enjoying the changing light over San Francisco.

The generous primary suite includes two walk-in closets and a Calacatta marble bath with dual vanities, soaking tub and separate walk-in shower. Positioned on the opposite side of the residence for privacy, the second ensuite bedroom captures southern and western views through two walls of floor-to-ceiling glass.

Additional features include in-home laundry, triple-zoned air conditioning, abundant storage and one-car valet parking, with guest parking available.

Life at the St. Regis extends well beyond the residence itself. Arrive home and hand the car to the valet. Have dinner sent upstairs through 24-hour in-room dining, meet friends for a drink at the St. Regis Bar, book a treatment at the newly renovated 9,000 sq.ft. Remède Spa or rely on the concierge and butler teams to handle the details. It is a level of service that allows the residence to function as a home while much of the work of maintaining a lifestyle is handled for you.

Residents also enjoy the hotel’s fitness center, lap pool, Astra restaurant and Tea Salon, along with a landscaped owners’ terrace with cabanas and 24-hour security.

Residence owners are also eligible for elevated Marriott Bonvoy status and select owner-exclusive travel, hotel, dining, wellness and lifestyle privileges across Marriott’s global portfolio through the ONVIA Owner Recognition Program.

In less than one second, buyers form an impression from the first image they see. We then have only two more seconds to reinforce interest through the remaining images, video, and floor plan — all before the decision to visit in person.

That is why every property we represent is photographed by a professional, never on a phone. Each shoot starts with staging coordination and a custom shot list, and is timed for natural light. Interiors and exteriors are captured by day and again at evening, along with aerial, cinematic and short-form vertical video. Images are captured carefully at the lens, so the home buyers see online is the home they walk into.

Shown: the dining room at 188 Minna Street, No. 34A, The St. Regis Residences, photographed by day and at evening.

From my referral partner Susana Carreira in Sintra, Portugal

Quinta da Alegria is a magnificent 18th-century country estate in the picturesque town of Sintra, Portugal, a UNESCO World Heritage site located 30 km from Lisbon. The property features a 10-acre (about 4 hectares) park, landscaped with stone terraces, lawns, reflecting pools, and century-old trees. Adjacent to the Quinta is the historic Seteais Palace, a magnificent neoclassical palace that is now a five-star hotel. The main house, with 12,486 square feet (1,160 sqm), consists of four levels, including the basement. There is an elevator from the basement to the third floor. It has 6 bedrooms and 7 bathrooms. The library, one of several grandly decorated reception rooms, features an outstanding 18th-century painted ceiling, depicting the Ascension of Christ. There are two guest houses: one with three bedrooms, three bathrooms, a large sitting room, and a kitchen, and another guest house with one bedroom and one bathroom. Additionally, there is a caretaker's house with two bedrooms, two bathrooms, a sitting room, and a kitchen. The magnificent 18th-century manor house was formerly called Quinta da Cruz and was designed by Daniel Gildemeester, the Dutch consul in Portugal. The grand façade of the manor house is punctuated by French doors and balconies. Acquired by a princely Austrian family and restored to its original splendor in 2007, the two-year restoration earned a prestigious certificate as a property of national interest. Beneath the terrace of the main house is a heated swimming pool highlighted by a coat of arms made from traditional blue tiles adorns the wall. The park retains its original 18th-century design. Many trails wind through the terrain, offering views over the plain to the Atlantic Ocean and the castles of Sintra. Along the way, you'll pass meter-high ferns, camellias, rose gardens, hydrangeas in various colors, and the "Citrus Grove," which has oranges, tangerines, and lemons. There is much to discover, such as fountains, ponds, ruins, and a grotto overlooking the lake, which is the centerpiece of Quinta da Alegria. At the bottom of the property, you'll find a garden with various types of cacti and a vegetable garden with a variety of vegetables and flowers. Sintra is known for its romantic palaces, historic estates and stunning landscapes. Perfect for a peaceful retreat or prestigious investment.

Multiple offers. Over asking. At the St. Regis, a result the building hasn't seen in years. Pricing and positioning made the difference at 34A, and downtown buyers are responding to well-positioned homes again. If you've been watching and waiting, now is a good time for a conversation.

Designed around the skyline, Residence at 181 Fremont pairs panoramic glass-wrapped living spaces with sophisticated contemporary interiors and a two-bedroom-plus-den floor plan built for both connection and retreat. Set on the northwest corner of the tower, this approximately 1,605-square-foot residence unfolds beneath almost 10” ceilings, with expansive glazing extending through the living room, dining area, kitchen and bedrooms to keep the city and Bay continuously in view.

The layout balances openness with intimacy: living and dining spaces flow together along the glass, while an intimate, more enveloping den and office create a distinct retreat within the home. Fumed French oak floors extend throughout, complemented by Paldao wood entry doors framed in Calacatta Carrara marble and a custom oak corner media cabinet.

The open kitchen combines Brazilian Macaubas quartzite countertops with Valcucine glass cabinetry, integrated appliances and dedicated w**e storage — clean lines that keep the architecture and outlook central to the room.

Offering Price: $2,695,000
