I will arrive in Venice from the airport and depart via train to Milan in the early morning of my depature day.
Both accomodations meet my needs, it comes down to location. The rental in Cannaregio is on Calle Turlona and the one in Castello is near the ocean off Via Giuseppe Garbaldi. I'm not interested in the Biennale art exhibition. I'm mainly interested in walking around and checking out the city and people.
Cannaregio is physically closer to the train but further from water bus stops. I also like that there is a large CONAD supermarket nearby. Cannaregio has easy access to Arsenale and Giardini water bus stops but further from the train (more time on the boat but less walking to the train). It's not clear if Biennale will bring large number of tourists to this area, making it crowded or noisy.
What do you think?
