Peacefully positioned at the end of a cul-de-sac in North Arlington's sought-after Rock Spring neighborhood, this spacious home offers a wonderful combination of privacy, comfort, and room to spread out. A welcoming covered entry and handsome staircase set the stage for what's inside: generous living spaces, abundant natural light, and a floor plan that makes everyday living and entertaining equally enjoyable. Freshly painted throughout, with beautifully refinished hardwood floors on the main and upper levels, new luxury vinyl plank flooring on the lower level, and new carpeting in the secondary bedrooms, this home is refreshed and ready for its next chapter! The main level offers plenty of places to gather—or find a little quiet. The inviting living room features a cozy fireplace, while the separate dining room has space for a banquet-sized table. Go ahead, invite everyone! A room with fabulous built-ins offers the flexibility of a home office, library, or whatever suits your lifestyle. At the heart of the home, the spacious kitchen combines good looks with everyday practicality. Granite countertops, a generous island with breakfast bar seating, white cabinetry, stainless steel appliances, and an abundance of storage make cooking, gathering, and entertaining a pleasure. Just off the kitchen, the comfortable family room features a striking stone-surround fireplace and easy access to the expansive deck. Whether it's morning coffee, dinner outdoors, or a weekend gathering with friends, there's room for it all. Upstairs, the generous primary suite offers a lovely retreat, complete with a tray ceiling, dressing area, mirrored walk-in closets, and a spacious private bath featuring dual vanities, a jetted soaking tub, and a separate walk-in shower. Three additional bedrooms and two full baths, including a Jack-and-Jill bath, provide plenty of flexibility for family, guests, and changing needs. And there's more! The finished lower level, now featuring new luxury vinyl plank flooring, offers additional living space, a bedroom, and a full bath—ideal for overnight guests, extended stays, an in-law or au pair arrangement, or simply having a little more room to call your own. Outside, the peaceful cul-de-sac setting provides a welcome sense of privacy, while the expansive deck offers a wonderful extension of the home's living space. And the location? It's a North Arlington favorite for good reason!
