The windowed chef’s kitchen, fully equipped with state of the art appliances, a separate pantry, and a separate staffing entrance, offers ample space for culinary creativity. The adjoining formal dining room provides an intimate setting for guests. Exquisite design meets modern amenities with central air conditioning, in-unit laundry, and impeccable finishes throughout. This home has been thoughtfully renovated to provide the ultimate in luxury, while maintaining the architectural integrity of its classic design. 9EF is perfectly crafted for discerning individuals. This apartment provides a rare combination of grandeur and comfort. The prestigious 1 East 66th Street is a full-service building offering unparalleled hotel-style services.
