Set at the rear of this handsome 1920s boutique building, this one-bedroom-plus-den condominium offers an uncommon sense of serenity in the center of San Francisco. Outside is the hustle and bustle of the city. But beyond the secure entry gate, a gracious foyer and lobby greet you with a sense of peace and calm. The period details and seating recall an earlier era and set the tone for the building's enduring character. Take the elevator or ascend the broad staircase to the residence on the second floor. Inside, garden views and mature trees create a remarkably tranquil backdrop. Despite its downtown location, the home feels insulated from the city's thrum, with peaceful outlooks over neighboring gardens and private yards. Original architectural details remain beautifully intact, including tall baseboards, picture rails, and classic moldings. Newly refinished hardwood floors run throughout the home, while thoughtful updates bring modern convenience to the kitchen and bath. The kitchen features quartz countertops, stainless steel appliances, generous cabinetry, and ample workspace. The bathroom boasts a deep tub with a shower and double sinks. The flexible floor plan includes a spacious den well suited for a home office, library, or media room. Between the bedroom and den is an exceptionally large walk-in closet with built-in shelving and double hanging rods on both sides, providing storage rarely found in homes of this size. Residents enjoy a shared rooftop deck that provides a sunny retreat above the city, along with shared, free laundry facilities on the ground floor. The self-managed seven-unit association offers the benefits of a small, well-maintained community. With a Walk Score of 98, the location places Union Square, Polk Street, Nob Hill, neighborhood cafs, restaurants, shopping, fitness studios, and public transportation within easy reach. Enjoy the energy of downtown San Francisco when you want it, and retreat to a home defined by quiet surroundings, architectural character, and thoughtful updates when you don't.
