Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Corcoran Group.
Downstairs, a private rec room gives this Greenwood duplex a second room that could work as a media lounge, a home office, a creative studio or a personal gym. The lower level also has a half bathroom and the in-unit washer and dryer, so the room sits near the functional part of the home. I like a flexible room like that in a one-bedroom, because it takes some pressure off the bedroom and the main living space.
Upstairs, the great room is the main living area, with a modern kitchen and a full bathroom. There's generous closet and storage space throughout, which helps in a duplex where the floors are split and everyday items need a home on each level.
The apartment has a private outdoor space of 217 square feet, and it's described as suited to relaxing or entertaining. The building has a roof deck and an elevator, and the home has a dishwasher, a city view and a park view. You'll also find an on-site parking garage as part of the building.
Greenwood Heights puts the 36 St station, served by the D, N and R, about 4 minutes away on foot. Sunset Park is about 11 minutes away, and Sunrise Mart is about 8 minutes on foot for groceries.
