Description
Spanning the entire seventh floor of one of Park Avenue's most distinguished white-glove cooperatives, this magnificent residence unfolds with a sense of quiet grandeur, defined by its gracious proportions, dazzling light and superb layout. A private elevator landing opens to a gracious twenty-five-foot gallery, leading to a splendid enfilade of entertaining rooms overlooking Park Avenue. Extending approximately 90 feet along the avenue, these rooms include the grand Living Room, handsome Library and the corner formal Dining Room. A Powder Room is off the library. There are wood-burning fireplaces with exquisite mantles in the living room and the library. The exceptionally large windows and ten-plus-foot ceilings enhance the sense of sophistication and elegance throughout. The meticulously designed chef's kitchen is expansive and inviting, with six windows, a large center island, custom cabinetry, and an eat-in area perfectly situated below a wall of windows. Well-suited for a serious chef and larger-scale entertaining, the kitchen is equipped with two Viking ovens, a Miele cooktop, two Miele dishwashers, two warming drawers, two sinks, and a Sub-Zero refrigerator. A separate butler's pantry provides extra storage. A hallway off the kitchen is lined with extra closets and leads to the large staff room and laundry room. The private quarters are set off a wide hallway. Originally two bedrooms, the huge corner primary suite faces Park Avenue and south with beautiful views down the avenue. There is a large dressing area and walk-in closets. The marble-clad primary bathroom is very large and sunny. Two additional bedrooms are generously proportioned, each with an ensuite bathroom and ample closet space. A separate staff room on the ground floor and two private storage rooms transfer with the apartment. There is through-wall air conditioning throughout. Completed in 1926, 660 Park Avenue is a sought-after cooperative comprising twelve full-floor residences. The building offers impeccable service including doormen, porters and a resident manager. Financing is not permitted. There is a 2% flip tax payable by the buyer.
