Top-floor loft apartments at the unique Ansonia Storage Warehouse rarely come on the market, so youll want to check this one out.  It has original pine floors, 11 ceilings and exposed brick walls and is bathed in light year-round, thanks to its two skylights and oversized South-facing windows. The kitchen is outfitted with Bosch stainless steel appliances and marble countertops, while the large, renovated bathroom sports a custom vanity, storage space and a separate closet for the Bosch washer and dryer. Four steps up to the bedroom create privacy and a large undercroft for additional storage. Currently configured as  a one bedroom with separate living and dining rooms, the space can easily be converted to two bedrooms.   You can picnic either on the common finished roof deck watching the sun set over a spectacular stretch of Manhattan, the Hudson, and New York harbor or from your  own roof deck space, one of only two separately allocated in the building. The Ansonia Storage Warehouse is an elevator building 5 minutes from Park Slope's shopping, restaurants and the F train, and 1  blocks from wonderful Prospect Park, including the Grand Army Plaza Farmers Market. Call for an appointment and see for yourself.
