Description
Perfectly positioned on the North/Center Slope border, this unique 2BD/2.5BA triplex feels like a private townhouse. The main living area offers a south-facing living room with exposed brick, original woodwork, bay windows along with an open kitchen with space for dining. The custom-designed kitchen from German Kitchen Center is equipped with stainless steel appliances, including a GE Café range with built-in microwave, built-in Bosch dishwasher, and KitchenAid refrigerator, quartz countertops, Grohe faucet, ample cabinetry, and walk-in pantry/coat closet. A full bath with tub is located off the kitchen. Up the spiral staircase are two spacious bedrooms, including a primary suite with a walk-in closet and a renovated ensuite bath with subway tile, a glass-enclosed shower, and Toto toilet. The generously proportioned second bedroom is illuminated by south-facing bay windows and features built-ins and exposed brick. There are high ceilings and hardwood floors throughout the upper levels. The versatile lower level was fully redone in 2014, and features a spacious rec room that can be used as guest space, playroom, home office, gym, media room, creative studio, and more. There is also a half bath with penny tile floors and a cozy den/study area with mounted bookshelves and access to the patio and backyard that is shared with just one other unit. Sleek Runtal radiators are also found on this level. The boutique pre-war co-op comes with free laundry (easily accessed from the unit’s basement level), dedicated storage, and bike storage. The prime Park Slope location is within close proximity to Prospect Park, Grand Army Plaza, the 2/3 trains, Brooklyn Public Library, shopping along 7th Avenue, and the Park Slope Food Coop. Cats and small, quiet dogs are considered on a case-by-case basis.
