About 510 N St Sw #n422

Fully renovated from top to bottom, this light-filled one-bedroom residence at Harbour Square combines thoughtful design, exceptional storage, and one of Southwest Washington’s most distinctive residential settings. With approximately 777 square feet, 7 closets, and an open, spacious layout, N422 has been carefully updated for comfortable modern living. A wall of floor-to-ceiling glass fills the home with natural light and opens to a private balcony overlooking the Loggia Gardens and tranquil water garden. The renovated kitchen centers around a generous island with seating and abundant storage and features stainless steel appliances and a GE Profile induction range. An in-unit washer and dryer adds a convenience rarely found in older cooperative buildings. The marble bathroom features floor-to-ceiling finishes and a glass-enclosed shower. Additional upgrades include Lutron intelligent lighting, dual motorized window shades, and 3M sun-control window film—small luxuries that make a noticeable difference in everyday living. One of HARBOUR SQUARE'S greatest advantages is how much is included in the $1,257/month HOA fee. Unlike many condominium HOA fees, Harbour Square’s fee includes major expenses homeowners often pay separately, including property taxes, utilities, internet, cable television, water, sewer and trash, management, 24-hour services, capitol reserve, and onsite maintenance. When those costs are considered together, the monthly fee represents substantially more than building maintenance alone. Harbour Square offers much more than an apartment building. Its landscaped six-acre setting, expansive lawns, water gardens, walking paths, rooftop terraces, indoor swimming pool, fitness center, 24-hour gatehouse, and staffed front desk create a comfortable residential environment in the heart of the city. Residents who enjoy getting to know their neighbors will also find an active, friendly community and opportunities to take part in Harbour Square’s social life. And the location is hard to match. The Waterfront Metro is about a block away, as is The Wharf, with restaurants, shops, music venues, Arena and Anthem Stages, waterfront recreation, and water taxi service. Walk along the Washington Channel, head to the Smithsonian museums and National Mall, or continue on to the U.S. Capitol—all without giving up the quiet gardens and waterfront setting waiting at home. N422 offers a rare combination: a thoroughly renovated home, remarkable storage and thoughtful upgrades, an unusually comprehensive monthly fee, an engaged neighborhood community, and one of Washington’s most convenient waterfront locations.
