An utterly charming combination of Rosario Candela architecture and Mark Hampton style, this rare second floor, south facing maisonette is located in one of Park Avenue's best buildings.  There is a beautiful arched entrance off the building's mahogany lobby into the Foyer which has an enchanting staircase leading to the apartment.  Radiating off the second floor landing is the elegant Living Room which has elaborate moldings, hand stenciled walls and decorative fireplace.  A gracious, square shaped Dining completes the very stylish entertaining space.  There are two generous Bedrooms and Baths.  The Pantry and Kitchen open onto a large terrace and the staff area is further enhanced by a Laundry Room, Staff Room and Bath. This category of property is difficult to find:  a grand, small apartment in a premier building. Flip Tax: 3%.
