Running alongside Amsterdam Avenue in Harlem is quiet Convent Avenue, easily one of the prettiest thoroughfares in Manhattan and my vote for one of the top five citywide (yeah, I’m talking to you South Portland Avenue and Montgomery Place in Brownstone Brooklyn).
I think the southern end of the street, in the 130s and low 140s, is in the Hamilton Heights neighborhood. Once you cross over the 145th, it becomes Sugar Hill. Both parts are flanked by gorgeous row houses and churches. You’ll practically expect a hansom cab to trot by.
