Description

A rare offering awaits you an exquisite north-facing garden duplex in a pristine early 1900s brownstone, nestled on tree-lined 84th Street! What an exceptional opportunity to own a spacious, elegant 1,150 sq ft residence in a prime Upper East Side locale, brimming with prewar charm and details, and complemented by a wonderful private garden. This exclusive 2-story gem with 2 bedrooms and 2 spa-like full baths oozes character and is accentuated by high wood beamed ceilings, rich hardwood floors, gorgeous exposed brick and stone, and a wood-burning fireplace in the great room. Off the gracious entryway sits a large walk-in closet, lovely full bathroom and stunning open kitchen, richly appointed for the chef with white cabinetry, granite countertops and backsplash, and stainless steel appliances. The gracious main level is perfect for entertaining with its generous open-concept living and dining space, and extension through glass doors to the peaceful garden oasis. Enjoy barbecues and al fresco dining on the rear lower patio, with stairs that lead up to the tranquil patio garden. Back inside, a spiral staircase winds up to the second story of the home housing the sleeping quarters. The oversized master bedroom is a quiet, light-filled retreat with a huge custom-fitted walk-in closet. Aside it is the equally large second bedroom with its own sizable custom walk-in closet. Both rear-facing bedrooms have access to a refined full bathroom. Built in 1922, 421 East 84th Street is a handsome brownstone co-op building with 5 stories, 7 units, and common laundry. The prime location is near many local amenities including Carl Schurz Park along the East River, Whole Foods and Fairway Markets, The Met, 2nd Avenue subway, and the 4/5/6 trains. No dogs, sublets or pied-a-terres allowed.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
