Welcome to a spacious and beautifully updated colonial located in the desirable William Floyd School District. This impressive 4-bedroom, 3-bath home offers exceptional versatility, abundant natural light, and an entertainer’s dream of an outdoor oasis. Come inside to find a warm and welcoming first floor, where gleaming wood floors run throughout and multiple sitting areas create an effortless flow for everyday living or hosting guests. At the heart of the home is the kitchen, offering generous counter space, ample cabinetry, and room to gather. Sliding doors off the main level open directly onto the patio, extending your living space outdoors. The backyard is designed for relaxation and recreation alike, featuring a cabana, a beautifully maintained in-ground pool, and mature privacy trees that create a serene, resort-like setting. Upstairs, you’ll discover well-appointed bedrooms, including a bright and comfortable primary suite with a large closet.
