Description

Welcome to 21 East 90th Street, Apartment 9C

A rare opportunity to create your dream home in the heart of Carnegie Hill, this spacious five-room residence offers the trifecta of what makes a New York apartment special: views, wonderful bones, and an exceptional location.

Set in a prestigious pre-war, full-service, white-glove cooperative, the apartment is entered from a gracious semi-private landing, shared by just two apartments, into a large proper foyer. From the moment you enter, the expansive outlook and abundant light is immediately apparent, with views of a magnificent neighboring building, rooftops, open sky, and, most spectacularly, from one of the bedrooms, views toward Central Park and the West Side across the Reservoir. Wait until you see those sunsets!

The residence offers two oversized bedrooms, each with walk-in closets and en-suite windowed bathrooms, each equally easy to designate as the primary. The large windowed kitchen (housing the highly coveted in-unit washer and dryer), and adjacent breakfast room gives you plenty of space to be creative. The generously proportioned living room, centered on a decorative fireplace, provides an inviting setting for both everyday living and entertaining, while the formal dining room is large enough to comfortably accommodate many guests and celebrations.

One of the co-op's most distinctive conveniences is its service entrance, an enduring hallmark of classic Upper East Side living. Deliveries, groceries, dry cleaning, mail, and garbage can all be handled discreetly through the service door. The building also offers a full time doorman, a friendly and helpful support staff, live-in superintendent, and a small workout room, providing the level of service and convenience that define white-glove living.

Perfectly situated in the center of Carnegie Hill, 21 E. 90th St. welcomes pets and pied-à-terre living. There is a 2% flip tax and 50% financing is allowed. The coop benefits from stable commercial income keeping the monthlies lower than many other buildings in the neighborhood. There is FIOS available, and a dedicated storage bin transfers with the sale.

While in need of updating and ready for your vision, its generous proportions, pre-war character, excellent layout, and extraordinary views provide the ideal foundation for creating a truly exceptional home.

Just half a block from Central Park and Museum Mile, you are surrounded by the best of the Upper East Side: Madison Avenue's elegant boutiques and restaurants, recognizable names along with beloved mom-and-pop establishments, world class schools and museums, and convenient access to public transportation.

With its remarkable views, gracious proportions, exceptional building services, and prime Carnegie Hill location, 9C is a good fit for customers seeking a particular style of living.
