Venice: My room: this was supposed to be a 4-star but it was small, the floors creaked, and it was poorly lit. The staff was very nice, however.
Castello: The doors of Santi Giovanni e Paolo. They were closed for siesta or whatever the 2 or 3 closing hours in the afternoon are called.
Dorsoduro: Rio della Fornace from Fondamenta Zattere ai Saloni--on the way to Santa Maria della Salute
