Description

Enjoy the best of Brooklyn living right outside your front door. Don't miss out on this classic four story Carroll Gardens brownstone that has been lovingly cared for since the early 1970's by the current and only third owner. Almost all of the 1898 interior construction remains intact. Currently designed as an owner's triplex over a competitive garden rental, there are few properties in this price range that allow one to comfortably move right in and collect rent or use as a single family home. Appreciate the historical charm throughout the parlor floor with its traditional pier mirror, floor-to-ceiling windows, pocket doors and two gorgeous marble mantels. The two floors above the parlor have four very spacious and bright bedrooms plus additional side rooms for an office or potential walk-in-closet. Each floor has a full windowed bathroom;the top floor also features a washer and dryer. The garden apartment has a claw foot bathtub, marble mantle, sizable bedroom and access to your private garden oasis. A classic brick archway spanning the length of the full basement and building provides added support and is surrounded by the original stone foundation. The rear basement hatch has a light-well, which can be added in front as well. An easy transition to becoming a finished basement, media/work or child's play area. Located one block to Smith Street, a short distance to the happening Gowanus area or just up Union Street to Prospect Park. Close to so many great restaurants, cafes, family-owned shops and local boutiques. Enjoy the weekend farmer's market at PS 58 or head over to Brooklyn Bridge Park.
