A private elevator vestibule opens to the 34-foot gallery of this prewar thirteen room apartment that features a terrace of over 2000 square feet on the upper level. Perfectly located on Park Avenue in the 70's, the apartment has sunny south and west exposures with open city and Central Park views.  The oversized living room could easily accommodate a grand piano and several seating areas.  The formal dining room is almost square and has an incredible picture window facing the Park.  The four bedrooms include a spacious, corner master bedroom.  The kitchen, pantry, and staff area are expansive and have a flexible layout including three staff rooms with open western exposures. Upstairs a sitting room/ den opens to the recently restored, terra cotta tiled terrace which is truly extensive.  Included in the sale is a double maids room and bath on the upper level which can be accessed by the service stair or from the private terrace.  Please bring your architect and your landscape architect!
