this fabulous three story penthouse apartment feels like a house set on the top of a full service prewar building. from the elevator landing one enters the front hall which is graced with a staircase sweeping up to the bedroom level, and is lit from above by a domed skylight in the roof. the living room is warmed by a woodburning fireplace and is side by side with the formal dining room. their east and west exposures assure bright light all day long. together with the bookcase-lined library these entertaining rooms provide fabulous space for parties of any size. accessible from the front hall is a sunny office or double staff room with full bath. the eat-in kitchen is generously sized without having to compromise any other room. a laundry, 2 staff rooms and a staff bath complete the lower level. the upper level with its four bedrooms and four exposures is flooded with light. the huge corner master bedroom is one of the prettiest in all new york. facing south and west, it is bathed in light and opens onto the terrace. the nine foot deep terrace is lusciously landscaped and wraps around all four sides of the apartment. as if all this were not enough, a surprise bonus is a magnificent roof top terrace of huge proportions and an octagonal tower room with extraordinarily open city views down park avenue as well as to the west and north.
