About This Home

As of March 2025

Welcome home to the Brooklyn lifestyle at its best! This sun-drenched one-bedroom corner condo with private outdoor space in prime Park Slope is located on the second floor of a classic brownstone that converted to condominiums in 2007.

#3A features seven windows, beautiful oak floors, updated millwork, and outstanding finishes including a chef's kitchen with granite countertops, custom cabinetry, and full-size, high-end appliances (Miele dishwasher, Wolf range, Franke sink, Sub-Zero refrigerator). Additional features include built-in bookshelves, a windowed bath with whirlpool tub, tons of light from north, east and south exposures, and incredibly low monthlies.

Your private section of the roof deck is two flights up, where you can take in the stunning views of Manhattan and beyond. (This six-unit condo gives each unit its own private space on the roof deck.) It's a perfect spot for sunsets, entertaining and seasonal fireworks.

#3A is perfect for those seeking a true one bedroom home, pied-a-terre, or investment property in the very heart of Park Slope with all of the neighborhood's amazing shopping and dining on 5th and 7th Avenues, and beautiful Prospect Park only three blocks away.
