Description

A true rarity- a bright, high floor and perfectly renovated 4 bedroom home which boasts all of the special features of pre-World War I architecture, including 10 foot ceilings, extra large windows and beautifully square rooms, PLUS the convenience of modern comforts. Taken down to the studs and thoughtfully and meticulously renovated, there are four great bedrooms, three full baths, a beautiful windowed chef's eat in kitchen, through wall air conditioning, and open views! Off a semi-private landing, enter into a lovely gallery off of which the home flows. The fourth bedroom or library has a beautiful full bathroom (which is also a powder room) and faces north onto double wide and peaceful 86th St., basically a "cul de sac" off Riverside Park. The formal living room and dining room are adjacent, creating a wonderful open entertaining space but also delineated enough for more formal entertaining. The grand living room with decorative fireplace has an open north view onto tree lined 86th Street and the dining room has open south views into Midtown. These three rooms boast stunning new solid white oak herringbone floors, the rest of the apartment has new solid white oak strip floors. The fabulous kitchen is complete with 2 ovens, (a wall oven plus one under the stove) a 6 burner Wolf professional range, wine refrigerator, Sub-Zero refrigerator and freezer drawers and a Bosch dishwasher. There is endless custom cabinetry, generous pantry space, beautiful Carrera countertops and perhaps most importantly, a large eat- in banquet dining area. In the bedroom wing, two additional bedrooms share a beautiful bathroom with a tub, and there is a large linen closet and full sized, vented washer dryer. The primary suite is a tranquil oasis facing south into Midtown with a luxurious bathroom with double vanity, large glass shower with bench and 2 general closets. This home is both grand and practical, and located on a great block, close to the best transportation, food shopping, dining, parks and schools! The "Royal Summit" is a full-service cooperative built in 1915 by the architectural firm of Mulliken and Moeller and incorporated in 1981. Boasting one of the prettiest lobbies in the City, the cooperative comprises approximately 67 homes, housed in two identical and adjoining buildings (310 & 320 West 86th St) for maximum privacy and intimacy in each small building. The coop is in superb physical and financial condition, is pet friendly, has 24-hour doormen, a resident manager, various porters and staff on duty as well. There are storage bins and bike racks for rent. Please call for a private appointment.
