Description

40th-Floor Two-Bedroom with Sweeping City & Central Park Views

Upper East Side | Yorkville | Full-Service Condominium

Perched on the 40th floor of a full-service condominium, this sun-filled two-bedroom, two-bath residence offers sweeping panoramic views south to Midtown and west toward Central Park — iconic skyline vistas rarely available at this price point.

South- and west-facing windows flood the home with natural light by day and deliver a striking cityscape at night. The spacious living and dining area offers excellent flow and scale, ideal for both everyday living and entertaining. While some owners in this desirable line have converted to three bedrooms, the current two-bedroom layout provides a wonderful balance of openness, light, and livability.

The primary bedroom suite is a quiet retreat, featuring custom thermal and acoustic insulation with layered gypsum walls and ceilings. The second bedroom is generously sized, easily accommodates a king-size bed, and is conveniently located near the second full bath.

The kitchen features stainless steel appliances, granite countertops, and ample storage. Additional highlights include upgraded city windows for enhanced comfort and efficiency, excellent closet space, and through-wall air conditioning.

Residence 40K is well-maintained and move-in livable as-is, while also offering clear upside for buyers who wish to personalize finishes over time through thoughtful, selective updates. For those who prioritize light, views, layout, and long-term value — with the flexibility to renovate on their own timeline — this is a compelling Upper East Side opportunity.

Building amenities include:
• 24-hour doorman
• Valet services
• Landscaped terraces
• Bicycle storage
• Private playground
• Central laundry
• Nearby parking

Common charges include all major utilities, including electricity (and A/C), gas, heat, and water — a rare and meaningful value. Financing up to 90% permitted. Unlimited subletting allowed (12-month minimum). Current capital contribution: $93.04/month.

Ideally located near 91st Street and Third Avenue, close to the Q train and the 4/5/6 lines, Whole Foods, neighborhood dining, the 92nd Street Y, Asphalt Green, Museum Mile, Central Park, and the East River Greenway. Convenient access to major medical and wellness institutions including NewYork-Presbyterian/Weill Cornell, Mount Sinai, and Hospital for Special Surgery.

Perfect as a primary residence, pied-à-terre, or investment, Residence 40K offers a rare combination of height, light, iconic views, and flexibility in one of the Upper East Side’s most established condominium communities.

It's good to be home.
