A fully independent two-bedroom guest apartment offers a living room, kitchen, and bath, perfect for extended stays or multigenerational living. The three-car garage is complete with a full bathroom. A distinctive octagon-shaped vestibule connects the bedroom wing and serene primary suite. Two spacious ensuite bedrooms enjoy courtyard views, while the primary offers pool views, a large bath with sunken tub, and dual bath layout with separate closets.
