This classic Emery Roth-designed, Bing & Bing-built cooperative is located just west of Sutton Place on East 57th Street. Originally 16 stories plus a penthouse with four units per floor, many apartments have since been combined. A/B lines face south; C/D lines are smaller with northern exposures. The building features two internal staircases, a service elevator, and allows various A/C setups. Washer/dryers are only permitted if installed before 1989. With no summer work restrictions and a refined, elegant atmosphere, this coop reflects the timeless charm of its prestigious location.
