Here’s a huge four-bedroom, two-bath co-op for rent in a prewar building in Crown Heights. The 1,675-square-foot pad was gut-renovated in ’06 and has a clean, modern feel. There’s a formal dining room, a “library nook” and lots of closets. However one of the bathrooms is ensuite, which is somewhat inconvenient. What’s your opinion of it for $5,200 a month?
