More than 100 years ago, the NY Times suggested Sylvan Court as a spot to visit "if one is interested in seeing a quaint bit of old Harlem . . . there are several old-fashioned brick houses on both sides of the court and the entire atmosphere of the locality reminds one of some of the half-forgotten spots occasionally found in the Greenwich Village district." That description still rings true to some degree, though less so than a couple of years ago when the street was still unpaved. You can see some 2009 shots of the houses and the yet-to-be-fancily-paved roadway about halfway down this page.
