Nestled in one of San Francisco's most iconic and desirable neighborhoods, 3633-3635 Webster Street is a rare, legacy duplex that blends timeless Marina charm with exceptional opportunity. Lovingly held by the same family for over 80 years, this grand-scale duplex spans more than 4,200 square feet and features 5 bedrooms, 6 bathrooms, and classically inspired living spaces brimming with natural light and original character. Refinished hardwood floors, bay windows, and charming balconies evoke the grace of San Francisco's architectural past while offering the functionality for modern living. The upper unit is tenant-occupied, providing immediate income, while the lower unit will be delivered vacant, creating an ideal opportunity to live in the heart of the Marina while offsetting your mortgage. Generous living rooms, formal dining areas, and ample bedrooms, perfect for entertaining or multi-generational living. A three-car garage provides rare convenience, and the location? Unbeatable. Just blocks from the Palace of Fine Arts, Ghirardelli Square, Crissy Field, and vibrant Chestnut Street, with its boutiques, cafes, and fine dining. Stroll along the waterfront, picnic at the Presidio, or watch the sun set behind the Golden Gate Bridge. This is life at its most picturesque.
