Description

Location and light! This spacious and quiet 1 bedroom apartment in an elevator building is perfectly situated in the heart of all Park Slope has to offer. The living/dining room, with 2 large windows, is bright and airy. The updated eat-in kitchen has a window and Corian counters and backsplash. The generous bedroom with leafy tree views has a deep closet and built-in storage to keep you organized. Want a home office? The hallway widens to form a space amply sized for a desk and cabinets or shelves. Three closets provide space for the things you need to stow. And the location? Fantastic! There is so much going on nearby. Prospect Park is half-a-block away, as is the Farmers market at Grand Army Plaza. The Brooklyn Museum of Art, Botanic Gardens, and Brooklyn Public Library are nearby. 7th ave shops and restaurants are just down the street. 2/3 and Q/B subways are just minutes away. This is a quiet, well-managed and maintained pre-war co-op building with good financials. Laundry and bike storage are in the basement. And its pet-friendly: your dog will love the off-leash hours in the morning in Prospect Park.
