Description

Penthouse A at 99 Morningside: an extraordinary residence occupying the entire twelfth floor of one of South Harlem's most sought-after boutique condominiums, that offers panoramic views of Central Park, Midtown Manhattan, Morningside Park and all of Harlem.

Kept in near-pristine condition, this expansive four bedroom, two and a half bath home is bathed in natural light and provides 2,313 interior square feet and 884 square feet of private outdoor space, including its very own roof terrace with a built-in gas grill and water supply.

The elevator opens directly into the custom built foyer that then leads into the generous living and dining area offering spectacular views south over Central Park, Billionaire's Row and the buildings beyond. Extending the living and dining area to the north is the beautifully finished windowed kitchen featuring dark oak cabinetry with matching tone marble counter and backsplash, and a Miele appliance suite that includes a custom-paneled, side-by-side refrigerator, freezer and dishwasher paired with an electric wall oven, speed oven, gas cooktop and hood. There is also a 46-bottle, under-counter wine refrigerator.

A thoughtfully designed two-wing floor plan distinctly separates the living, dining, and entertaining areas from the private bedroom quarters, optimizing functionality, comfort, and privacy. A light-filled corridor connects the wings, passing the laundry room, a windowed powder room, and the staircase leading to the roof terrace.

Each bedroom is graced with its own stunning view, either south and west directly over Morningside Park and the Columbia Secondary School or north and east across all of Harlem. Of particular note, the gracious primary suite includes its own SW-facing terrace, the ideal place for morning coffee and starting the day, as well as a luxurious ensuite marble bathroom with a Moen soaking tub, separate glass shower stall and floor to ceiling window facing south. The three secondary bedrooms are all roomy and share a full bathroom.

Perched at the very top of the building, the impressively scaled roof terrace delivers wide-ranging views in every direction while also maintaining an unexpected sense of seclusion. Whether hosting unforgettable celebrations or cultivating a verdant sky garden, this rare outdoor retreat is as versatile as it is breathtaking.

Several thoughtful details complete the luxurious appointing of this exceptional home such as: mechanicals for a two-zone central air system so that the living area and bedrooms can be maintained at different temperatures, floor to ceiling thermally broken tilt-turn and casement windows that maximize energy efficiency, sound dampening and light, a rich dark oak flooring throughout and plentiful storage space.

A boutique condominium constructed in 2020, 99 Morningside benefits from a 421a Tax Abatement that expires in 2035 and consists of only 23 homes. Residents enjoy several amenities such as a part-time doorman from 6 pm to 11 pm, a video-intercom, a superintendent on premises during the day, a modern and fully equipped gym and bike storage.

Perfectly situated at the corner of Morningside Park and W 123rd St just minutes from Columbia University, this home places you in the heart of one of Manhattan's most vibrant neighborhoods. Within just a few blocks you'll find gourmet grocery stores, acclaimed restaurants, cozy cafés, and lively nightlife along Frederick Douglass Boulevard. Central Park is a short stroll away, and multiple subway lines offer an easy commute anywhere in the city.
