The finishes are light and bright in this renovated Greek Revival row house unit in Cobble Hill. The triplex offers a fair amount of space, modern updates like central air, and some period details like wide plank floors, black marble mantels, and a stair with curved railing. Price-wise, though, it isn't exactly a modest monthly outlay. The 25-foot-wide brick row house at 188 Warren Street sits in the Cobble Hill Historic District, whose designation report dates the dwelling to circa 1841.
