Rarely available, the D line has great entertaining space. The entry foyer can double as an office and leads to the formal dining room and living room which are separated by glass french doors. The apartment is at the back of the building and therefore it is peaceful with no street noise. The two corner bedrooms are both bathed in western light in the late afternoon. The layout of this Classic 6 lends itself to various uses for the main rooms.   If you want a 3rd bedroom, that would be an easy fix by putting up a wall and using the living room as a bedroom. Built circa 1922, this apartment has high ceilings, classic moldings, and original oak hardwood floors throughout. There are two full windowed baths; one with a tub in the hallway easily accessed by either bedroom and one with a stall shower in the staff/office room.    The kitchen is also windowed and has an original hutch which is charming but in need of removal of years of paint.   The kitchen has many possibilities for upgrading and changing the configuration.  Other units in the D line have been inventive and designed beautiful unique kitchens in the space. The cooperative has a full-time doorman and a live in super. Amenities include a gym, media room, laundry room and a very special landscaped roof deck with spectacular sky, water and city views.   The building is pet friendly, allows washer/dryers and CAC with board approval. Location is ideal with close proximity to both Central and Riverside Parks, local transportation and a wide choice of eating and shopping venues. There is an assessment of $270.23 per month through 10/27.
