Rarely available two bedroom two bathroom apartment in a boutique, prewar Upper East Side co-op, at a premier address between Park and Madison Avenues! The result of a combination of two adjacent apartments, Residence 3AD boasts a grand loft-like living room for entertaining brightened by four large windows facing south, high airy ceilings of nearly 11 feet, and a desirable split-bedroom layout for optimal privacy. Welcoming you in is a large and gracious entry gallery that can easily serve as a dining room, with a wet bar and a windowed kitchen conveniently adjacent. Customize this spacious beauty to your vision, and you’ll have a dream home to enjoy for years to come! Beautiful hardwood floors, open archways, generous front and rear bedrooms, a windowed bath, and abundant closets make living here even more desirable, washer/dryer possible. Currently two separate apartments that have been combined, a buyer may choose to legally combine them.
