This wonderful duplex, decorated by Markham Roberts has the charm of a graceful old world apartment with lots of light and pretty exposures. Downstairs is a large gallery which opens to a beautifully proportioned living room facing onto Park Avenue. A beautiful wood paneled library with powder room and a dining room that can easily seat 20 are gracefully arranged off the gallery. A large chef’s kitchen with room for serious cooking and a table for family dining as well as a generous staff room and bath complete the floor. A charming, architectural staircase leads you to the private upstairs bedrooms. Upstairs is an open and airy, very large corner master bedroom facing Park Avenue with excellent closets and a generous bath plus two additional large bedrooms with tons of light and a shared bath.

9B at 784 Park is such a special residence. The apartment is in lovely condition and beautifully appointed by one of New York’s most respected and in demand designers in a top white glove doorman building on 74th and Park in the most coveted little section of the Upper East Side. Moments from Central Park and surrounded by the loveliest restaurants, coziest cafes, best museums and wonderful shopping.
