Description

Enjoy Park Slope living at its finest in this wonderful loft-like duplex with a huge private deeded rooftop terrace, perfectly located moments from Prospect Park. Residing in a handsome, intimate townhouse cooperative, 3B is truly rare and beautiful, uniquely designed and graciously laid out with separate entertaining and sleeping quarters. The 2 bedroom, 2.5 bath dream home is brimming with distinctive features, such as vaulted ceilings, vintage lighting fixtures, tasteful built-ins, walnut doors with bronze hardware, oversized windows and skylights, imported cement encaustic tiles and radiant heated bathroom floors.

The main level is perfect for entertaining, with a gracious dining room and open chef?s kitchen appointed with wood cabinetry, and premium stainless steel appliances including a newer dishwasher. Off the dining area sits a spacious sunken living room for relaxing and hosting guests, featuring sunny northern windows and a charming wood-burning fireplace. The upper level houses the lovely master bedroom retreat offering generous closets and an en-suite bath, plus a 2nd bedroom brightened by a wonderful skylight. Abundant closets throughout the home are custom-outfitted by Elfa and can easily be reconfigured if desired. Other highlights are Runtal radiators, a new 2020 Mitsubishi mini split AC system, washer & vented dryer, crawl space storage in the living room, plus basement and bicycle storage in the building. The ultimate outdoor pleasure is yours on the fabulous roof terrace offering plenty of room for lounging and dining areas. Have great summer barbecues in your own outdoor getaway.

Once the headquarters of the Long Island Automobile Club, the striking art nouveau elevator building is pet friendly and the ideal location. Zoned for PS 321, and steps to Prospect Park, Grand Army Plaza and farmer?s market. Also nearby is the Brooklyn Museum, Botanic Garden, excellent shopping and dining, and the 2/3, B/Q, N/R subway lines.
