IN CONTRACT - Take the elevator to the top floor of this elegant turn of the century brownstone to see this mint 4 room apartment brimming with pre-war charm and character.  High ceilings, crown molding, two wood burning fireplaces and hardwood floors are complemented by a renovated kitchen and bathrooms.  The gracious living room is anchored by a wood burning fireplace with lovely marble mantel and French doors onto a Juliet balcony with views of lush townhouse gardens.  A windowed den/guest room and dining area with custom sideboard flow from the living room. There is a spacious master bedroom with sunny, south facing exposures, working fireplace and a skylit, ensuite bath.
