El Sereno Drive is one of San Carlos's best-kept secrets. Tucked away on a cul-de-sac in the heart of coveted White Oaks, it offers an unmatched sense of peace and seclusion while remaining just steps from local schools, Caltrain, Laurel Street, and Trader Joe's. Homes here are rarely available and this updated California ranch pairs an exceptional location with an expansive lot and refreshed living space. Inside, an updated chef's kitchen features natural quartzite countertops and premium Thermador and Bosch appliances, and a formal dining room connects seamlessly. Both rooms flow naturally into the living room where a wall of French doors draw you outside to embrace effortless indoor-outdoor living. The Hawaiian-inspired, resort-like backyard unfolds with a pergola-covered patio, pebble-bottom pool with waterfall and spa, built-in fire pit, two lawn areas, an outdoor shower, and lush citrus trees. The tranquil bedroom wing features a primary suite with an updated bathroom and walk-in closet, while two additional bedrooms share a remodeled hall bath. A separate flexible suite with an exterior entrance offers options for guests, extended stays, or office space. This is a rare opportunity to own a home that so effortlessly blends seclusion, location, and resort-style living.
