A jewel within the elegant and very chic James Berwind Mansion, the dramatic duplex apartment in New York City boasts some of the grandest rooms on Fifth Avenue. Meticulously restored, the Beaux Arts masterpiece displays many of the original details. Thirteen-foot ceilings distinguish the ravishing haven, lending volume and importance to the graceful interiors. Mahogany and gilt bronze embellish the resplendent living room. Another highlight is a light-filled conservatory crowned with a dramatic glass ceiling. A mahogany and brick-arched wine cellar holds 4,000 bottles of the noblest wines. Culmi-nating the romance are three beautiful bedrooms with two marble baths and a private grotto garden that lends enchantment outdoors.
