About this home

Located just blocks from downtown San Mateo and with access to acclaimed South Hillsborough Elementary School, this circa 1906 Craftsman presents time-honored architecture combined with numerous updates for today's lifestyle. Sheltered from the street by two gated driveways, and bordered by a gently flowing creek, the home presents exquisite period details like coffered ceilings, elaborately carved fireplaces, and to-the-floor windows that take full advantage of the beautiful setting. Luxurious amenities include a gourmet kitchen and family room combination, remodeled bathrooms, a large office that doubles as a media room, plus a temperature-controlled wine cellar. Upstairs, there are 4 spacious bedrooms and with a total of almost 4,000 sqft, there is ample room for today's work-from-home needs. Outside, the verdant grounds of more than 1/3 acre comprise numerous outdoor venues with vast decks, a spa, and level land for creekside recreation and gardening.
