Description

Perched on the 18th floor above Lenox Hill, one of the Upper East Side's most coveted areas, this exceptional home offers expansive outdoor space and sweeping skyline views. Originally two separate apartments, the A and B lines were thoughtfully combined into a spacious three-bedroom residence with triple exposures. A gut renovation transformed the residence with a newly appointed kitchen, two beautiful bathrooms, upgraded electrical, and the addition of an in-unit washer/dryer. The windowed chef's kitchen is outfitted with Smallbone cabinetry, custom storage, and a double sink, alongside a Bertazzoni range, Sub-Zero refrigerator and wine fridge, Viking microwave, and Miele dishwasher. One of two wood-burning fireplaces is seamlessly integrated into the dining area. The second fireplace anchors the living room, where northwest exposures frame unobstructed skyline and sunset views. Exit onto the wraparound terrace, an extraordinary luxury that lets you take in both sunrise and sunset from your own home. The bedroom wing is privately positioned away from the entertaining areas. The primary suite opens onto the outdoor space and includes a five-fixture bathroom. The secondary bedroom features custom millwork and built-in bookshelves by Little Wolf. The third room is a windowed home office with a built-in Italian-made Murphy bed, offering flexibility as a guest room or optional third bedroom. 205 East 78th Street is a classic Art Deco cooperative. Residents enjoy a 24-hour doorman, live-in superintendent, laundry room, bike room, and rentable private storage. Building highlights include: - Maintenance includes electricity and gas - Subletting permitted for up to two years total, with one-year renewals - Pied-à-terre, co-purchasing, and guarantors permitted Located moments from Central Park, the Metropolitan Museum of Art, Madison Avenue shopping, and multiple transportation options, the location places the best of the Upper East Side within easy reach. Additional notes: - Capital assessment of $932/month through December 2026 - 2% flip tax (or $20 per share, whichever is greater)

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.
