We really liked Brian's Appartment. He was really kind. He even checked if we are okay because there was high rise of water during our stay and provided waterproof boots for us.
It was super clean and tidy. We had everything we needed.
The Appartment is near the center and you reach everything within a 5-15min walk. The Cannaregio region is really beautiful and full of nice little restaurant.
We highly recommend this apartment if you stay in Venice.
P.S. Check out the most narrow street (Calle Varisco, 52cm). It's only 5min away!
