Over the past few years, this sliver of a neighborhood tucked against energetic Atlantic Ave. has become a haven for TV and movie stars looking for peace and quiet away from prying eyes. This should tell you something about Boerum Hill’s livability and the quality of its housing: Brick townhouses and three- or four-story buildings dominate the tree-lined blocks. Boerum Hill tends to slip under the radar, and that’s how its residents like it. While cafés and fine dining abound, as they do in nearby Cobble Hill, the neighborhood enjoys a low profile. Residents love the convenient location and subway service, as well as the preponderance of independent businesses.
