Last week we compared the two Brooklyn neighborhoods of Park Slope and Windsor Terrace. Park Slope is probably best known for its turn-of-the-century brownstones, but in the mix is also this small, three-story brick apartment building on Montgomery Place, built in 1920. The building is not so small when you consider that, as the Daily News reports, it was originally constructed as a single-family mansion for the wife of a prominent banker.

The building is exactly a block from Prospect Park, and now divvied up into nine condos. This week's condo pick is one of the nine, a four-bedroom, two-bath duplex, and it appears to have been recently renovated. It's listed for $2.995 million by Warburg Realty, and is outfitted with modern, upscale fixtures and finishes. It also comes with its own private roof deck.

You enter into a foyer that leads to the open living and dining area, which looks airy and well-lit and includes a large closet and built-in shelving. There's additional dining space at the breakfast bar in the kitchen, along with decent storage space and high-end appliances, including a new Viking stove.

Three of the four bedrooms are also on this level, and while two of them appear a bit narrow, they have closets, and are currently set up as kids rooms. A third bedroom is bright thanks to its corner position, and is configured as a den. There's a walk-in closet off of this room, as well as one full bathroom.

Upstairs, the master suite features a wall of closets in the bedroom and a bathroom across the hall. Just outside is the private roof deck, which offers plenty of space for outdoor dining.

Other perks include central air, an in-unit washer and dryer, and what looks like generous closet space throughout. The building is about five blocks from the 2 and 3 trains at Grand Army Plaza. Pets are permitted.
