Look out on treetops and a historic church instead of a brick wall. This gut-renovated Park Avenue corner apartment in Murray Hill offers four bedrooms plus a playroom, three full baths, high ceilings and sunny south and west exposures. It's a rare quiet, green outlook in Midtown, about five minutes on foot to Grand Central. A 30-foot living and dining room opens to a chef's kitchen with Ernestomeda cabinetry, a vented Wolf range, Sub-Zero refrigeration and Miele appliances. The primary suite has a marble bath with an oversized rain shower, a sitting area with a working wood-burning fireplace, and a built-in home office. A separate playroom works as a den, office or guest space. All three baths have windows. The renovation includes four-zone Mitsubishi central air, 5-inch white oak floors, Dornbracht fixtures, a Bosch washer/dryer, built-in speakers, remote-controlled shades and custom closets throughout. 67 Park Avenue is a full-service prewar co-op with a 24-hour doorman, an attended elevator, a roof deck and bike storage. Pied-à-terres and pets are permitted. The seller pays the 2% flip tax. Bryant Park, Park Avenue South dining and the 4/5/6/7/S trains at Grand Central are steps away.
