Situated on the 3rd floor of a historic, Queen Anne style brownstone, this delightful home is bright, airy, and abundant with both original features and thoughtful, architect-designed upgrades..

The bathroom also features more custom built-ins, which provide ample storage along with housing a large stacked washing machine and dryer. On entering the spacious and peaceful master bedroom, you'll pass additional contemporary custom closets and will find another large closet in the bedroom's interior. Just off the master bedroom, is another room that can be used as an office, den, or nursery. With original hardwood floors and high ceilings throughout, this is a charming, inviting home. The apartment comes with an oversized, dedicated storage area in the basement where there is also common laundry. This delightful self-managed co-op benefits from low monthlies and is pet friendly (cats are welcome, dogs on approval).
