Situated on a picturesque tree-lined street in the heart of San Marino, this charming traditional home has been lovingly maintained by the same family for the past 38 years and offers timeless elegance with warmth and character. A brick walkway leads through manicured greenery to the inviting front porch, creating a welcoming prelude to the home. The formal entrance features wainscoting and a custom antique clock. To the right of the foyer, the elegant formal living room is filled with natural light from expansive bay windows overlooking the front gardens, while a classic fireplace creates a warm focal point. The space flows seamlessly into the formal dining room adorned with a traditional chandelier, wainscoting, and wall-to-wall custom built-in display cabinetry--ideal for intimate gatherings and holiday entertaining. To the left of the foyer is the private sleeping wing featuring a spacious primary suite, two additional bedrooms, and a convenient hallway bath. Detailed with wood-paneled walls and custom built-in bookcases, the library offers the perfect setting for a game of Mahjong or Bridge or simply a quiet reading retreat. A charming Dutch door opens to the bright sunroom with walls of windows overlooking the backyard, creating a pleasant indoor-outdoor connection and a comfortable space for everyday living or relaxation. Adjacent to the sunroom, the kitchen offers generous cabinetry and convenient access to the formal dining room through a classic pocket door. A separate service porch with a laundry area, access to the covered back porch and an additional bath provides practical functionality and leads to the rear portion of the home, where a comfortable den and fourth bedroom offer flexibility for guests, extended family, or potential for conversion into a junior ADU. The covered porch connects to the workshop, detached two-car garage, and extra parking area. The private backyard features a sparkling pool, cabana, and mature landscaping, offering a wonderful setting for relaxing outdoors or entertaining family and friends.
