A Parlor-Floor Jewel Box in the Heart of Park Slope! Welcome to 427 9th Street Apt 2. This stunning, sun-drenched one-bedroom co-op occupies the coveted parlor floor of an intimate four-unit brownstone in the heart of prime Park Slope. Soaring ceilings over 10 feet high and oversized south-facing windows create an impressive sense of scale and fill the home with beautiful natural light, while original architectural details bring warmth and unmistakable pre-war character throughout.

Newly refinished hardwood floors, updated lighting, and stunning chandeliers bring elegance and sophistication to the space while highlighting its gracious proportions and original details.
