This week's top listings include a variety of unique touches, from a double-height library to stained glass, an enclosed wet bar and exposed stonework. They span a wide array of neighborhoods, including Brownsville, Midwood and Sunset Park, and the prices also have quite the range, starting as low as $499,000 and going as high as $4.248 million (or, in the case of the single rental on the list, $6,900 a month).
