Description

This classic eight-into-seven-room home, located in one of Manhattan’s most prestigious residential addresses, has ?undergone a sophisticated and impeccably tailored renovation by renowned interior designer Phillip Thomas. With 10-foot ceilings, beautifully preserved architectural details, and grand proportions throughout, this sun-filled residence is truly exceptional. Entering from a semi-private landing, an elegant foyer unfolds into a stately entrance gallery, making a gracious first impression. Beyond, the impressively scaled living/dining room, anchored by a wood-burning fireplace, flows seamlessly into a handsome library. Stretched across sunny Madison Avenue, this expansive public space is equally suited to large gatherings and relaxed evenings. A large eat-in kitchen is ideally situated off the gallery and thoughtfully designed for everyday life, featuring a Wolf six-burner range and Miele appliances, wonderful storage, and banquette dining. Adjacent to the kitchen are a separate laundry room, butler’s pantry and bar—details that make the apartment as functional as it is beautiful. The private bedroom wing is tucked away from the entertaining spaces and also enjoys quiet, sunny exposure. The serene primary suite includes a separate sitting area, dressing room, generous closets, and an en-suite bath. Two additional well-proportioned bedrooms share a renovated bath and offer excellent closet space. A separate staff room with its own full bath provides ideal flexibility as a guest room, office, or additional bedroom. Located on the most sought-after stretch of Madison Avenue, 33 East 70th Street and 30 East 71st Street are sister addresses that share one of Manhattan’s finest white-glove cooperatives. Built in 1928 by Schwartz & Gross, residents enjoy impeccable service from a 24-hour doorman, porters, and live-in resident manager, as well as a newly renovated lobby and fitness center, private storage, bike storage, and in-building laundry. Ideally situated on East 71st Street and Madison Avenue, it is moments to Central Park and to many of the best museums, galleries, boutiques, and restaurants on the Upper East Side. The building is pet-friendly and permits 50% financing. A 2% flip tax is payable by the purchaser.
