This spacious and unique five is one of the best values around.  It has almost 40 feet on the park, a huge living & dining room combination, and a windowed kitchen that is also on the park.  The western light is terrific.  Two full and quiet bedrooms, two baths and enormous closet space complete the living space.  There is also a washer/dryer installed in the apartment.   These features and amenities notwithstanding, perhaps the most extraordinary feature is the almost unbelievably low maintenance of only $460.  The building is extremely well run as evidenced by its low maintenance and excellent physical condition; its wonderful planted roof deck, large children's playroom, and bike and general storage augment this fine home.   The area is perhaps the most sought after on the Upper West Side  --   combining a serene residential lifestyle with the energy of the Columbia University community, and all enhanced by new luxury condominium developments, cafes & restaurants, entertainment and shopping.
