Description
From the moment, you enter this warm and gracious south facing garden duplex you will feel at ease. The soothing color palette of this 1,322 square foot convertible two bedroom with 1.5 baths plus enormous private garden will immediately make you think this is the perfect place to call home. The sun filled open living/dining area is complete with sliding glass door that gracefully flows into your own true private urban oasis. The massive two-tiered garden is over 800 square feet allowing for enough room to plant flowers, herbs and vegetables. Enjoy beautiful nights lounging outside with family and friends on your patio, which is perfect for entertaining a large group with plenty of room for a table of eight, BBQ grill, additional sitting area and perhaps even a fire pit!
Adjacent to the airy and bright living/dining area is the well-appointed kitchen complete with custom cabinets, a soothing glass backsplash, Caesarstone counter tops and Bosch appliances. Quietly tucked away in the back of the apartment is the tranquil and spacious master bedroom that looks out to the garden. The serene and modern full bath upstairs features designer tiles and Kohler fixtures. Other hallmarks include a full laundry closet, two more hall closets and a large walk in closet. Downstairs you will be in awe finding an oversized den that could work perfectly as an additional bedroom plus plenty of room for an office or additional living space. This unique level has a window that allows southern light to pour in from the garden above and is completed by a stylish half bath enhanced with cool black and white penny tiling and high-end fixtures.
Ideally situated in a boutique 5-unit condominium building in vibrant Greenwood Heights close to Prospect Park, shopping and transportation. Minutes from local favorites such as Lot 2, Guissepena's, Quarter Bar and Toby's this special home is not to be missed.
Presently zoned for PS 10.
