Description

Perched atop a pre-war elevator building on one of the quietest tree-lined blocks on the Upper East Side, this duplex one-bedroom, one-and-a-half-bath residence is the one that ends the search — including a wood-burning fireplace you didn't know to ask for. Soaring 13-foot ceilings and sun-drenched skylights set the tone from the moment you step inside. The generous living room faces south, flooding the space with natural light and offering ample room to entertain. The open kitchen is appointed with granite countertops and stainless steel appliances, while a powder room off the foyer adds everyday convenience. Upstairs, the private bedroom suite is a true retreat — featuring its own skylight, southern exposure, high ceilings, a large walk-in closet, an additional closet with built-in desk, and a windowed en-suite bath. Storage is anything but an afterthought up here. 425 East 78th Street is a boutique six-story cooperative with virtual doorman, live-in superintendent, residents' garden, laundry room, and building-wide surveillance. Maintenance covers property taxes, heat, hot water, gas, and internet at a subsidized rate — an exceptional value. The building welcomes pied-à-terres, guarantors, parental purchases, and gifted units. Subletting is permitted for up to five years following two years of owner occupancy. Pets welcome up to 25 lbs. Units like this are rare. Don't let it be someone else's - contact me today to show!

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.
