Updates complement the home's architectural integrity, including refreshed flooring, upgraded kitchen surfaces and appliances, improved paint, and enhanced bath fixtures.Set on a private 1.85-acre lot with mature trees, a detached garage, gated parking, pool and spa, a separate casita with its own bath, and paid-off solar for energy efficiency.
