Description

RARE and NEW to the Market, 45 Martense Street #6B is the only top floor three bedroom in Brooklyn priced under $1M and it is in the Jewel of Flatbush, 45 Martense Street, a prime Flatbush pre-war co-op near dining, excellent transportation and Prospect Park. There is no property with the bright sunshine and size (over 1,600 square feet) of 45 Martense Street #6B and with all of its pre-war Art Deco charm and amenities: on the top floor with sunny southern, western and northern exposures, 45 Martense Street #6B has the flexibility of layout and space that are must-haves in the current Brooklyn market. The recently renovated Art Deco lobby of 45 Martense Street welcomes you to the newly-replaced elevator up to the top floor of the co-op where 45 Martense Street #6B unfolds in all its Art Deco splendor: a welcoming foyer leads to a classic center Dining Hall flanked by arches to an enormous Living Room with southern light and a recently renovated (new refrigerator, new dishwasher) eat-in, windowed Kitchen allowing an opportunity to dine in two separate spaces. The recently spruced-up bathroom has a coveted separate soaking tub and shower stall and is also windowed. The entire apartment was recently painted as well and there are seven closets, one of them a walk-in large enough for a nursery. 45 Martense Street #6B is not "currently configured" or "modified as" a three bedroom, it is a true three bedroom with two ultra-king sized and one queen-sized bedrooms: the primary bedroom is corner-windowed and sized for a king bed, with space for a sitting area and a crib if needed. Art Deco touches include a bookcase alcove and two walk-in closets, a luxury available to few. The second bedroom is also king-sized with two closets and is large enough to be used as an office for two, or an elegant professional space. The third bedroom is queen-sized and supports space for an office or sitting area as well. The entire apartment is complimented by original hardwood parquet floors dating to 1937 which are in excellent condition. The luxury of over 1,600 square feet, very low maintenance, on the top floor of an elevator building with Art Deco details in a well-managed and financially secure co-op should appeal to any buyer seeking a solid investment in Brooklyn. With the proximity to the B,Q,2,5 and S trains along with Brooklyn's pride and joy, Prospect Park, 45 Martense Street #6B must be seen and will not last. Please make an appointment with the exclusive broker today. Martense Street is a quiet, tree-lined one-way street four blocks to four major train lines and express buses. With a bustling dining scene including Bonafini, Risbo, Parkside, Loud Baby, Brooklyn Perk, Mango Seed, Zurilee and new restaurants emerging constantly, Flatbush is a destination for Brooklynites in the know. It's a short stroll to Prospect Park, the Brooklyn Botanic Garden, the Brooklyn Museum and Kings Theater making Flatbush a cultural and recreation destination as well. 45 Martense Street has a bike room and storage rooms ($5/$65 per month), central laundry, Verizon Fios, common lounge and a backyard garden with communal BBQs. Full-time live-in Super and financially secure co-op make for a great home, community and investment.

Flatbush features one of Brooklyn's most varied housing stocks, including grand detached Victorians along Ocean Avenue, limestone and brownstone rowhouses, prewar apartment buildings, and brick townhomes within landmarked districts like Prospect Park South and Ditmas Park. The Q, 2, and 5 trains connect the neighborhood to Manhattan, while Prospect Park's 526 acres of green space border the northern edge. The restored Kings Theatre, a 1920s-era landmark performance venue, and Erasmus Hall High School, founded in 1786, are among the area's most notable architectural features.
