Property Description

With 16-foot ceilings and soaring arched windows overlooking Union Square Park, this home offers scale, light, and drama that are simply unmatched. The expansive living and dining space flows into a custom chef’s kitchen with professional-grade appliances, marble island, and bespoke finishes—perfect for both entertaining and everyday living. Each bedroom features an en-suite bath with refined stone and wood finishes, while a powder room and full laundry room add convenience.

Situated directly on Union Square Park, this boutique condominium places you at the center of downtown’s most vibrant neighborhoods. The Union Square Greenmarket, Whole Foods, and some of Manhattan’s best restaurants—including ABC Kitchen, Gramercy Tavern, and Breads Bakery—are at your doorstep. A true transportation hub, the N, Q, R, W, 4, 5, 6, and L trains are just steps away, with the West Village, Flatiron, Gramercy, NoMad, and Washington Square Park all within walking distance.
