Description

Welcome to Apartment 6A, a top-floor loft residence at 425 East 78th Street on the Upper East Side. A rare two-level layout, this home features a skylight-topped sleeping loft open to the living area below, giving the studio the volume and light of a much larger space. The main level centers on an oversized living area with hardwood floors, a wall-mounted television, and oversized windows fitted with a built-in storage over the radiator. A custom built-in desk nook sits tucked beneath the loft staircase, with a wood-tread stair leading up to the sleeping loft above. The eat-in kitchen includes white cabinetry, a gas range and oven, over-range microwave, and a mosaic glass tile backsplash, plus a movable island with pendant lighting for additional seating and storage. The home features ample storage space, with a large coat closet in the foyer, a walk-in closet in the living room, and further cupboard storage positioned in the loft. The bathroom is finished in marble tile flooring and walls with a black granite vanity top. 425 East 78th Street is a boutique prewar cooperative dating to 1910, with an elevator, live-in superintendent, laundry room, and a beautifully landscaped residents' garden, a rare outdoor amenity for the Upper East Side. The building permits guarantors, co-purchasing, Gifting, Pets, Pied-a-Terres, and allows subletting (You must own two years, then you many sublet three out of every five years). Located between First and York Avenues, the building is central to neighborhood shopping, dining, Jay Park, and the Second Avenue Subway (Q) at 72nd and 86th Streets, with easy access to crosstown buses and the FDR Drive. Don't miss this rare chance to make this one-of-a-kind home your own!

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.
