What I liked
San Marco piazza full of tourists and weddings, the shopping area with souvenirs for your friends, the Murano glass everywhere, the pigeons and of course, the canals. The Ghetto is a less crowded place I'd love to have a coffee again. And of course, the seafood.
What I didn't like
...that I only had a day to see everything, and did not manage to rest, relax, and see Venice in all its splendor. Also, did not see the canals by night :(
