Description

Open, bright, and airy, this spectacular 2-bedroom, 1-bathroom boutique condominium delivers an exceptional, pre-war-inspired layout updated with every modern convenience. Unit 5 features pristine hardwood floors throughout, central heating and air conditioning, a virtual doorman, and the ultimate perk: in-unit laundry. The heart of the home is a fully appointed, windowed chef’s kitchen equipped with sleek stainless-steel appliances, including a gas range, dishwasher, microwave, and full-sized side-by-side refrigerator. The surprisingly spacious living and dining areas flow effortlessly, leading up to the true crown jewel: a remarkable private roof deck oasis featuring stunning bridge views. Both well-proportioned bedrooms serve as peaceful retreats, each offering generous layouts that easily accommodate full-bedroom sets and deep closets for excellent storage. Set in a private, all-brick building, this top-floor treasure is an easy two flights up, ensuring quiet evenings with no neighbors above you. Residents enjoy a peaceful retreat with seamless access to the very best of Bay Ridge and Dyker Heights. You are just moments away from local dining favorites, lush parks, the Dyker Beach Golf Course, and the newly revitalized 86th Street shopping corridor. As an added financial bonus, a J-51 tax abatement is active through mid-2028, and public transportation options are plentiful.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
