4 East 66th Street, designed by the renowned architect J. E. R. Carpenter at the apex of his celebrated career and completed in 1920, is one of the Upper East Side's finest addresses. Its handsome yet simple limestone facade belies the splendor of the apartments within. Setting a standard for refined luxury, the building's original design included eleven simplexes, one on each floor, all benefiting from glorious views over Central Park, just across Fifth Avenue. In close proximity as well are many of New York's very best shops, museums, galleries, and restaurants.

From far above the treetops, this elegant apartment features spectacular open vistas over the park's dramatic seasonal foliage changes from a pair of exceptionally large reception rooms. Soaringly high ceilings, magnificent views, a windowed Gallery, and open views in four directions impart a wonderful brightness to the residence.

Accessed by private elevator landing, the impressive, south-facing Gallery has a baronial sensibility and opens to the very grand Living Room and Library, each with a wood burning fireplace and divine direct views over Central Park. Connected by two wide paneled doorways and with a monumental sense of openness and proportion, both rooms benefit from glorious light: the Living Room's windows face east, south, and west; the Library's north and west. At the opposite end of the Gallery, a very large and stately paneled Dining Room also has a wood burning fireplace and exquisite hand-carved architectural detail. Also accessible from the Gallery is a Reception Room/Bedroom, currently configured as an office with an ensuite bathroom, as well as a Powder Room and coat closet.

Beyond, a chef's eat-in Kitchen with state-of-the-art appliances, ample storage, and marble countertops and backsplashes accesses a back corridor. Back-of-house is comprised of a convenient Gym with an ensuite Powder Room, a large Laundry Room, a Double Staff Room with an ensuite bathroom, and HVAC and mechanical rooms.

The elegant private quarters are separated from the rest of the apartment by a long hallway lined with ample closets. A marvelous and very spacious Primary Suite is comprised of a wonderful corner Bedroom with open views and a wood burning fireplace, two very generous Dressing Rooms with ample closets, two beautifully-appointed marble bathrooms, and a large Sitting Room, also with a wood burning fireplace. There is an additional Bedroom with an ensuite bathroom and a very ample closets, including a walk-in Dressing Room.
