Description

Welcome to 334 Union St, #3 — a tastefully renovated two-bedroom, one-bath condo within a charming townhouse. Located in prime Carroll Gardens with easy access to transportation, restaurants, parks, and the endless amenities that define the neighborhood. This recently renovated floor-through apartment has the modern conveniences you're looking for including AC, in-unit washer/dryer, dishwasher, and a voice intercom virtual doorman for security. The open floor plan seamlessly connects the living, dining, and kitchen areas, creating a great space for entertaining. The modern kitchen is clean and sleek and the new bath is townhouse-classic with a soaking tub. East and west-facing oversized windows bathe this top floor space in light while exposed brick, hardwood floors and ceiling beams add warmth and character. Both bedrooms are well-proportioned offering comfort and tranquility. A small terrace brings in just enough of the outdoors. Connecting to the existing solar system is an option. The building has a water filtration system that removes over 95% of particulate matter, chemicals and minerals. Located steps away from the F and G trains, Carroll Park, and a plethora of shopping and restaurants on Smith and Court Streets — too numerous to name! Note that monthly taxes are currently approximated.
