About this home

Mission Highlands is the hidden gem just a couple of minutes above the Plaza. Single level 3 bedroom + office/2 bath main house plus detached 1 bed/1 ba guest house. The property has what many will say are the best views in Mission Highlands. Walk through the meandering flagstone path of mature landscaping and majestic Oaks on this 3/4 + acre property, you are greeted by postcard perfect sweeping views of the Valley. Walls of floor to ceiling glass overlooking the rolling lawn and views beyond. Light & bright interiors with hardwood floors, vaulted ceilings, updated kitchen with commercial grade appliances, fireplace, barrel ceiling in hall, and both views & french doors from nearly all rooms in the house. Above the detached 2 car garage is a large 1 bedroom unit with full kitchen. Hot tub, stone walls, hobby vineyard, overflowing gardens and flowers. Solar owned. A magical setting and rare find. Hot tub and perfect spot for swimming pool.
