Description

PREWAR CLASSIC SIX ON A BEAUTIFUL PARK BLOCK

NEW TO MARKET! A gorgeous classic six with all open exposures on a prime Carnegie Hill park block just moments away from Central Park's Engineer's Gate and the city's most beautiful museums, in one of the neighborhood's finest prewar cooperatives. Enjoy the park's most beautiful entrance, a visit to the Guggenheim, Metropolitan and Jewish Museums or a peaceful moment in the publicly accessible and furnished gardens of the Cooper Hewitt Smithsonian Design Museum, all at your feet.

Off a semi-private landing, residence 8B at 21 East 90th Street is a grand and glorious corner apartment offering 2 bedrooms, 3 bathrooms, a windowed eat-in kitchen and a perfectly customized home office, all with open views from every window overlooking Madison Avenue and tree-lined 90th Street.

A sprawling living room stretches nearly 24' wide, hugging the corner of the building and drawing in fabulous light and vistas over Madison Avenue to the East and 90th Street to the South. At its center is a gorgeous marble fireplace surrounded by all custom stone and millwork as well as an elegant custom bookshelf along the western wall and high beamed ceilings overhead. The living room opens to an avenue-facing dining room with adjacent dry bar, creating a seamless experience for those who like to entertain at scale.

Immediately adjacent, a large windowed eat-in kitchen features a built out breakfast nook with booth seating, a wealth of counter space, custom cabinetry and storage and is adorned with beautiful glass subway tile backsplash. There is a 36" Subzero refrigerator with double freezer drawer, GE Profile oven and range, concealed Miele dishwasher and Subzero wine fridge as well as a washer/dryer discreetly tucked away in the rear corner of the kitchen. Also in this part of the home is a wonderfully outfitted home office with an en-suite windowed full-bathroom overlooking Madison Avenue, easily converted into an additional bedroom as per your needs.

The West wing of this home has all southern exposures over glorious East 90th Street and consists of two large bedrooms, each with its own en-suite windowed bathroom with radiant heat flooring and extensive custom storage and built-ins throughout. Like the rest of the rooms in this home, the bedrooms are also wired for sound.

Located in one of the city's most coveted neighborhoods of Carnegie Hill, on a prime park block just moments from Museum Mile and the city's grandest entrance to Central Park and the Jacqueline Kennedy Onassis Reservoir, 21 East 90th Street is a top-tier full-service prewar cooperative built in 1927 by George F. Pelham. The building enjoys unparalleled proximity to the best of New York City's cultural and educational institutions as well as phenomenal shopping and dining. Residents are afforded the benefits of a full-time staff including doorman and live-in resident manager. There is also bike storage, central laundry and private storage for each apartment. Pets are welcome. 2% building flip tax payable by the purchaser.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, 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.
