Villa Montebella, the 2024 Vacation Property of the Year, is newly refinished and perfect as a residence, home for multigenerational living, or vacation mecca. The compound, which lives as an 8-bedroom estate, comprises 5 buildings. Surrounding the buildings are a vineyard, pool, hot tub, bocce court, play area, pool house, palms and other mature trees, and a 4860-sq-ft wine cave. Enter over a private drive winding through oaks, madrones and oleander. Privacy is absolute, and yet the estate s entrance is just a mile from world-class dining and wineries. The centerpiece of the living areas is the Main House, under beamed ceilings. It features the principal suite, 2 other bedrooms, a huge dining room and living room (under skylights, with a wood-burning fireplace), and refinished terraces. The kitchen features tile counters, elite appliances, and breakfast-bar seating for 8-10. The other bedrooms are found in the other buildings: the hexagonal Lighthouse (with an office and THX movie theater), Penthouse (with a living room and decks), Vineyard House (with stunning views of ripening cabernet grapes), and Tennis House (adjacent to the court that could be configured for pickleball). There is a charging station for EVs; a generator for emergency power; and ample well water.
