Description

The quality of its design and the vibrancy of its location ensure this one-bedroom cozy apartment's lifestyle appeal is absolutely irresistible. Conveniently positioned in the heart of Park Slope with all the attractions along 5th Avenue within a few footsteps, it offers a very private retreat that is supremely easy to maintain and situated in the Brooklyn?s best shopping and dining options. The easycare floor plan will have a big impact on buyers who demand value for money. There is a generous and bright living and dining space with hardwood flooring, tall 9-foot ceilings and double hung windows that capture leafy street outlooks. The modern kitchen is well appointed with stainless steel fittings, and there is a peaceful double bedroom with built-in closet space and large south windows that face away from the street. The apartment comes complete with a well-proportioned bathroom with deep soaking tub plus a separate washer dryer, as well as a large deeded storage unit in the basement. Residents here enjoy close proximity to great coffee at Starbucks, Whole Foods Market, as well as JJ Byrne Playground, Prospect Park and a choice of Manhattan subway lines. The boutique condominium building of only 10 is pet-friendly with a J-51 tax abatement in place until 2024. This is the perfect pad for inner-city professionals as it offers easy access to all corners of the city, and has eateries, cafes, transport and acres of parklands close by. It is immaculately presented throughout and ready to move in and enjoy straight away.
