25 Sereno Place sits on a quiet cul-de-sac in West Vallejo, offering sweeping hill views and a unique blend of timeless character and modern versatility. This generously sized 4-bedroom, 3-bath home combines its original 1955 charm with a thoughtfully designed lower-level addition, creating flexible living space across two full levels. Warm hardwood floors and a marble-tiled gas fireplace welcome you into the main living room, where a large picture window frames neighborhood rooftops and the rolling hills beyond. The kitchen continues the home's classic appeal with rich wood cabinetry, dark granite countertops, and new stainless steel appliances, including a stove, microwave, and dishwasher. It opens seamlessly to a bright dining area overlooking the backyard. Upstairs, the primary suite features a private ensuite bath, accompanied by two additional bedrooms and a full hall bath. Downstairs, you'll discover a truly one-of-a-kind retreat wrapped in a stunning designer wood ceiling, highlighted by under-lit lighting, sleek black porcelain tile, and plush broadloom carpet. Whether used as a second primary suite, private lounge, media room, or guest quarters, this exceptional space offers endless possibilities. The adjoining full bath elevates the experience with a sunken jetted tub, designer porcelain tile flooring, and a luxurious rain shower features rarely found in a home of this era. Every detail of the addition reflects thoughtful craftsmanship and custom design. The converted garage has been transformed into a soundproof music room, offering a versatile space that could also serve as a home office, art studio, gym, or hobby room. Step outside into your own unique, private garden sanctuary, where the beautifully landscaped backyard comes fully furnished and is ready for entertaining. Whether you're hosting a large gathering or enjoying a quiet evening, this outdoor space offers something for everyone. Relax in the private spa, unwind beneath the shade of mature trees with a good book, or fire up the BBQ and enjoy family and friends. The spacious yard also offers plenty of room for gardening, with space to grow your own vegetables alongside mature fruit trees and bushes, including pear, apple, plum, orange, blackberry, and Concord grapes. Complete with a covered patio, comfortable sectional seating, lush turf lawns, and mature landscaping. Minutes away from the Vallejo Ferry with easy access to SF.
