Listing Notes

Situated on iconic 3rd St in the heart of Park Slope, 409 3rd St, Unit 4 is an updated 3-bedroom, 2-bathroom condo located in a classic Brooklyn brownstone. Perched on the top floor of a charming low-rise building, this stylish home seamlessly blends timeless charm with modern conveniences. Beautiful herringbone hardwood floors greet you as you enter the home, which is flooded with abundant natural light from both northern and southern exposures, and two skylights. The home features an open layout that creates a warm and airy atmosphere. The expansive primary suite boasts a custom walk-in closet, while the additional bedrooms offer flexibility to suit your needs. The unit offers the convenience of a washer/dryer, split system air and heat, and a hydraulic roof hatch. An internal staircase leads you outside to your private roof deck, the perfect space for entertaining or simply unwinding while taking in stunning skyline views. 409 3rd St puts you steps from some of Brooklyn's best. Grab a slice at Emmy Squared, your morning cup at Hungry Ghost Coffee, or a seasonal farm-to-table dinner at Stone Park Cafe. Prospect Park, JJ Byrne Memorial Park, and the Grand Army Plaza Greenmarket are all within easy reach for your green space fix, and with the F, R, G, N, and W trains at 4th Ave/9th St and the B and Q at 7th Avenue, getting anywhere in the city is a breeze.
