At the center of the home, the kitchen and family room connect seamlessly, anchored by a generous island that serves as a natural gathering space. Upstairs, the primary suite offers a quiet retreat with a spacious layout, walk-in closet, and spa-inspired bath. Three additional bedrooms and two bathrooms complete the upper level, providing flexibility for family and guests. Conveniently located near the 57 and 60 freeways, and just minutes from top-rated schools, dining, shopping, and parks, this home combines comfort, scale, and location.
