A Smartly Updated Upper East Side Studio Discover a studio that makes excellent use of its space at 425 East 78th Street, Apartment 4D. North-facing and thoughtfully updated, this Upper East Side home pairs distinctive prewar details with modern finishes. The layout gains character from a step-down living area, creating a natural separation within the home. High ceilings and hardwood floors enhance the space, while the renovated kitchen is finished with quartz countertops and stainless-steel appliances. The updated bathroom features a spa-style soaking tub-a welcome touch at the end of the day. 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. Set between First and York Avenues, the building offers convenient access to neighborhood restaurants, shopping, parks, the East River and transportation. Pets up to 25 pounds are permitted.
