This third-floor co-op with elevator is the epitome of efficiency in layout and design. The kitchen with breakfast bar opens to the living room, and the bedroom is quite large — big enough for a king-size bed. The listing is shared by Michael Jacobs and Michael Patterson of City Wide Apartments.

Two majestic fireplaces with original detailing — one in the living room (working) and the other in the master (decorative) — contribute to the grandeur of this Park Slope co-op, which is in an 1880s brownstone close to Prospect Park. Based on the number of saves, it already has a parade of prospective buyers in hot pursuit. Listing by Debra Bondy and Sally Marmet of Compass.

It’s easy to see why this is a hot listing. First, it’s a duplex, which provides more freedom to roam. Plus, it has great features such as a wood-burning fireplace, private terrace and central AC. And it comes in a 36-foot wide, 1830s mansion in historic Brooklyn Heights. Elliman’s David Glick is the listing agent.

For the buyer who desires that picture-perfect NYC apartment, this neat ‘n’ tidy 1-bedroom co-op could be it. There’s also historic appeal: It was designed by John B. Snook, the guy who designed the original Grand Central Depot, predecessor to today’s Grand Central Terminal. Listing by Peter Forsman and Bradley Rodenberg of Douglas Elliman.

This Park Slope duplex is a bit of an anomaly, standing apart from the neighborhood’s usual historic vibe. But if you’re looking for space, it’s all here: 1,525 square feet and two spacious terraces. Listing by Saul Shapiro, Marta Maletz and Michael K. Davis of Compass.
