Finally, the top-floor offers a bright & spacious 2 bedroom / 1 bathroom rental unit with formal dining room in move-in condition.Built in the 1890's, this home is one of the most intact brownstones to be offered for sale in the neighborhood in many years, as evidenced by the remarkable original details such as carved wood railings, wainscoting, exquisite wood moldings and doors, plasterwork, tin ceilings and parquet floors. The many upgrades, including ample custom built-ins and closets, make this home fitting for today's lifestyle, and as an extra benefit you'll find not only the first-floor extension but a bone-dry, full walk-out basement.  This lovely house is located on a beautiful tree-lined street with well-kept brownstones & brick townhomes from one end of the block to the other. Transportation is a breeze with the N express stop at 59th Street. The property will be delivered vacant. Exclusively listed by The Corcoran Group.
