Tucked away at the top of desirable Guido Street, this expansive Mid-Century Modern retreat offers a rare blend of privacy, versatility, and iconic Bay views. Signature vaulted wood ceilings and massive windows equipped with motorized blinds frame the bright, open floor plan, creating a warm yet airy atmosphere anchored by beautiful hardwood floors. This central gathering space flows seamlessly out to a private patio, which features a full outdoor kitchen designed for the ultimate indoor-outdoor entertaining experience. The main level continues with three comfortable bedrooms, including a primary suite with a private ensuite bathroom, all positioned for easy, convenient living. Downstairs, the lower level provides ultimate flexibility. It can be used as one large cohesive extension of the home, or the layout can be split so the primary room serves as a spacious family room while the two additional bedrooms, second kitchen, second laundry, and private entrance form a separate, self-contained apartment—an ideal setup for rental income or multi-generational needs. Additional highlights include abundant storage and a two-car garage. Located just minutes from the "Red Park" playground, the shops and dining of Montclair Village, and the world-class hiking and mountain biking trails of Joaquin Miller and Roberts Regional parks, this home perfectly balances secluded hill living with top-rated schools and neighborhood convenience.
