Considering the Il Giardino di Giulia in Venice?

Canali piccoli e stretti by croisbeauty
The network of Venetian canals is amazing, there are great number of small, short and narrow canals and each one looks more beautiful than the previous one you have seen. Those which are very short and narrow can be reached by boats only. I wish I could seat in my own boat and explore them all, it might be great adventure.
