Description

21 East 87th Street, #7B Spacious, light flooded, prewar, 9-room apartment in prime Carnegie Hill location, this gracious property has the original floorplan and has been beautifully maintained by the same family for about eighty years. It formerly housed a magnificent, world renowned collection of Old Master drawings. One enters the apartment through an elevator vestibule, shared by one other tenant, into a large foyer leading into a grand, east-facing living room with decorative fireplace and two large, double-hung windows overlooking Madison Avenue. The adjacent formal dining room, easily seating twelve, is linked to the kitchen by a butler’s pantry with sink, refrigerator and dishwasher. In the eat-in kitchen, there is a washer/dryer and, off it, two maid’s rooms with a connecting bath. The four good-sized bedrooms, all accessed from corridors off the foyer, face south and have ample closet space. The primary one, serviced by a large fitted dressing room closet, is situated on the corner and therefore also has a wonderful, additional eastern exposure and a view overlooking the Park Avenue Synagogue. It has an en suite bathroom with separate shower and bathtub. One of the three bedrooms also has a small bathroom en suite, while the other two (one now used as a library) have a larger connecting bathroom that also provides a powder room for the apartment Apartments in the B-line of 21 East 87th Street rarely come on the market. Designed by Emory Roth in 1927, this building, situated near some of the best schools, restaurant and museums in New York City, is one of the most sought-after on the upper Eastside. It is a full-service building with resident super and full-time doormen, as well as such amenities as a gym, a central laundry, bike storage, and a private storage unit. There is a 2% flip tax. 65% financing permitted. Current monthly assessment of $515.08 through 2026.
