Description

Welcome home to this rarely available generously scaled classic 7 apartment, fabulously situated in a sought-after full-service prewar condominium in prime Carnegie Hill, one block from Central Park and defined by enviable natural light, open city views from three exposures, charming architectural details, and an ideal layout providing the perfect setting both for grand entertaining and intimate gatherings. The grand entry gallery opens onto the gracious sun-filled living room featuring high beamed ceilings, southern cityscape views over double-wide tree lined 96th Street, crown moldings, ample space for multiple seating arrangements, and anchored by a lovely wood-burning fireplace. Flowing beautifully from the living room and separated by French doors, sits the stately dining room which also functions wonderfully as a media room/den, or as a combination dining/casual living space. The windowed kitchen is fully equipped with stainless steel appliances, Caesarstone quartz countertops, and boasts a separate windowed breakfast room. The private bedroom wing includes the corner primary bedroom with a wall of closets, an ensuite bath with new vanity, and sunny open views south and east. The two additional bedrooms are well-proportioned, both sharing an adjacent bathroom also with a new vanity. The bright staff room has an ensuite windowed bathroom with stall shower, and could also be utilized as an office, guest room or fourth bedroom. An in-unit washer/dryer, hardwood floors, impressive storage space, including a giant walk-in closet in the bedroom corridor which could serve as an office complete this not to be missed gem. Pets are welcome and private storage transfers with the sale. The entire apartment has been freshly painted, ready for you to move right in or make your own! Built in 1924, this established white-glove building offers residents top service and amenities including a full-time doorman, live-in resident manager, attended elevator, state-of-the-art gym, playroom, spectacular roof deck, and private storage. Perfectly located, 55 East 86th Street is just off Museum Mile and minutes to Central Park, the city’s best private and public schools, restaurants, boutiques, and transportation. *The two secondary bedroom photos are virtually staged.

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.
