A rare find in this market, this stunning three-bedroom limestone condo penthouse duplex on prime 4th Street offers a lovely modern living space with 10 foot ceilings and high-end finishes throughout. It has been meticulously and recently renovated to provide the best of today's amenities with all the benefits of townhouse living without the fuss. The first level offers a large open room with extensive living/dining space, a kitchen with an island, high-end appliances/finishes and separate seating and dining areas perfectly overlooking the treetops with southern exposures. A magnificent custom built-in bookshelf/storage unit covering an entire wall provides the purchaser with a host of design/storage possibilities. There are two bedrooms on this floor and an oversized bathroom with cool mosaic tiles and custom cabinets. A stackable washer-dryer and utility closets are perfectly integrated into the bathroom space. An open stairway leads you to the ultimate master bedroom penthouse suite with 10-foot-plus ceilings and walls of windows on both sides. Exquisite built-in closets offer incredible amounts of closet space. The expanse of the space allows a buyer the option to create a home office adjacent to the north side terrace. Sliding glass doors take you to two perfectly planted terraces facing north east and south west. Together they provide over 500 square feet of additional entertaining space-a breath-taking urban refuge from which to observe glorious sunrises and sunsets! Other amenities include central AC/Heating, as well as a dedicated and functional common storage space in the basement. Low common charges and taxes (not abated) of approximately $900/month combined. This is truly a shrewd and inspirational purchase for buyers looking for a house alternative in one of Park Slope's best locations. Just a short distance to all the major subway hubs, Prospect Park, and the restaurants along 5th and 7th Avenues, the location could not be more convenient. It is zoned for the much-vaunted public school 321, admission to which is highly coveted.
