Description
Park Slope Perfection on a Coveted Park Block. Set on the second floor of a beautifully preserved boutique co-op, this bright and airy 2-bedroom, 1-bathroom home seamlessly blends timeless pre-war romance with modern Brooklyn living. The layout offers a rare and thoughtful separation of spaces. Once inside, the residence instantly captures your attention with classic character, featuring rich hardwood floors, warm exposed brick, and abundant natural light across three exposures. The open kitchen flows effortlessly into the dining space, creating an inviting environment for casual weeknight dinners and seamless entertaining. Large enough to accommodate formal dining for eight, or a comfortable home office, this space holds many possibilities. Completely distinct from the dining area, the formal living room serves as a sophisticated, private retreat. Anchored by two monumental windows overlooking leafy 15th Street, this elegant room offers an intimate view of the treetop canopy and a tranquil backdrop of changing seasons. Both bedrooms serve as peaceful sanctuaries, feeling private as they are located on opposite sides of the apartment. The classically tiled, windowed bath is thoughtfully updated, and the adjacent linen closet includes a highly coveted in-unit laundry hookup. Enjoy easy access to the park's Long Meadow at the Southwest entrance of Prospect Park at Bartel-Pritchard Square as well as the 15th Street F/G subway station. This mortgage-free boutique building offers an unparalleled lifestyle. The best of The Slope's celebrated dining, cafes, and culture is right at your doorstep, and a large private storage unit in the basement transfers with the unit. Additional amenities include a laundry room and a bicycle room, both located in the basement. 427 15th is formally included in the Park Slope Historic District Extension, and your pets are welcome to join you in this park-block home.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
