Description

Welcome to this thoughtfully renovated duplex two-bedroom with a sprawling private outdoor space and extraordinary walk-in closet, just steps from Riverside Park! The top floor of this true HOME offers an open chef’s kitchen, complete with an inviting breakfast bar, dishwasher, and an abundance of custom cabinetry, a wonderful living and dining area accented by built-in shelving and storage, plentiful with natural southern light, a double-exposure, queen-sized secondary bedroom, and a marble powder room. Down the custom-built, curving staircase, one finds the marvelously private and pin-drop quiet primary suite. Enjoy a king-sized bedroom with custom shelving, a grand, custom-built, walk-in closet and dressing room, and a luxurious marble bathroom complete with a soaking tub and steam shower. Additional interior features include mini-split central air, recessed lighting throughout, a generous entryway closet, wide-plank hardwood flooring, and a laundry room right outside the apartment door (though the building does also allow in-unit washer/dryers). The crown jewel and ultimate NYC amenity is the private backyard, spanning over 500 SF (two separate areas), providing plentiful room for a full dining table, separate lounging area, and a grill, ideal for evenings entertaining friends or quiet mornings with a cup of coffee in your own sanctuary, surrounded by eucalyptus and native elms.  The possibilities are endless. The co-op has just completed a major capital improvement project, including upgrades to the roof, HVAC, plumbing, boiler, security system, and façade, ensuring long-term value and enhanced comfort for residents. The building allows co-purchasing, guarantors, parents buying for children, pied-à-terre ownership, pets, and subletting with board approval. Nestled in a classic brownstone on a lovely residential block, which is adorned with peach blossoms in the springtime and friendly, familiar faces year-round. Wonderfully situated half a block from cherished Riverside Park—enjoy tennis, running, bicycling, sledding, picnics, and so much more. The quintessential New York neighborhood offers a mix of historic charm and modern amenities with Whole Foods, Trader Joe’s, and the neighborhood Greenmarket a stone’s throw away and a number of trains—A,B,C,1,2,3—just steps from home. The immediate area is also brimming with fabulous dining establishments, outdoor cafes, world-class cultural experiences, authentic shops, playgrounds, and a true sense of community.
