Welcome to this beautifully upgraded waterfront residence at Harbour Square, where exceptional privacy, refined smart-home enhancements, and tranquil garden and water views come together in the heart of DC’s Southwest Waterfront. This stylish 1-bedroom, 1-bath home offers an open, light-filled layout with floor-to-ceiling sliding glass doors leading to a private balcony overlooking the lush Loggia and water garden beyond. Rental parking available!

Residents also enjoy rooftop terraces with sweeping views of the river and monuments. Inside, the home blends comfort and sophistication with wood flooring, custom built-ins, and a seamless flow that is equally well suited to everyday living and effortless entertaining. The kitchen is thoughtfully designed with granite countertops, a spacious island, stainless steel appliances, and a GE Profile induction range. An in-unit LG washer and dryer add convenience. The generously sized bedroom is tucked privately away from the main living area and features three closets, creating a peaceful retreat with excellent storage. The updated bath is finished with floor-to-ceiling tile, a sleek modern vanity, and a glass-enclosed shower.

A standout feature of this residence is its thoughtful collection of premium upgrades. The Lutron intelligent lighting system offers customizable scenes, remote control, scheduling, and automated lighting adjustments. Additional enhancements include 3M sun-control window film and Bali dual motorized roller shades with both room-darkening and solar functionality. Together, these upgrades materially enhance comfort, convenience, efficiency, and overall appeal, elevating the home into a more premium category.

What truly sets this home apart, however, is its remarkable sense of quiet. Reinforced concrete construction on all four walls, as well as the ceiling and floor, creates exceptional sound insulation and a rare feeling of calm, privacy, and permanence that is increasingly hard to find in city living.

Storage is another rare advantage, with seven closets, additional storage, and bike storage in the building.

Harbour Square is a historic, pet-friendly cooperative set along the Washington Channel on beautifully landscaped grounds with reflecting pools and gardens. This amenity-rich community offers indoor pool, fitness centers, 24-hour concierge service, outdoor grills, laundry facilities, electric vehicle chargers, rental parking, bike storage, and additional storage. The monthly co-op fee includes all utilities, cable TV, high-speed internet, property taxes, maintenance, reserves, building insurance, and more, creating an exceptionally convenient and comprehensive ownership experience.

Just moments from The Wharf, Arena Stage, Nationals Park, Audi Field, The Anthem, Safeway, CVS, and the Southwest Farmers Market, this location offers the very best of waterfront city living. With easy access to Metrobus, water taxis, Waterfront Metro, and L’Enfant Plaza, commuting throughout DC, Maryland, and Virginia is effortless.

Experience a rare combination of waterfront serenity, substantial construction, modern convenience, and vibrant city access at one of Southwest’s most distinctive communities.
