From the listing:
Enter a private elevator landing on the 26th floor with double access entry to the apartment for a feel of separate yet commodious wings. The entrance gallery, on the south side of the penthouse floor, meets a 51-foot-long expanse of glass windows flanking one of the four terraces. Off the long gallery is an elegant powder room, a home office/den with an exquisite wet bar that then leads to a spacious living room with a gas fireplace. At the other end of the gallery, and off same terrace, is a full dining room adjacent to an eat-in kitchen with two Bosch dishwashers, two Viking wall ovens, a Sub-Zero refrigerator, and picture windows with partial views of the Hudson River. Moving along, the north side of the penthouse features a large and gracious conservatory/reading room or second dining room (commonly used for dinner parties.) which is approached by way of the commodious pantry, laundry room and wet bar. Relax or entertain on the second terrace, featuring an outdoor plasma TV, with access to an elegant library with a second gas fireplace. Deeper into this wing of the apartment affords an exercise room, plus two guest bedrooms, all three rooms have en suite baths. Up a lovely staircase in the penthouse duplex is a luxurious owners' Oasis: The spacious primary suite with two huge closets and a grand primary bathroom with double sinks, steam shower, crystal chandelier, onyx floor and counter tops, plus a separate study, and a 14'X17' dressing room (each of which is sizeable enough to be a very comfortable sixth bedroom). All this and two more landscaped terraces on this upper level.
