I would highly recommend staying at Leone’s place if you’re visiting Venice. It is centrally located and easily accessible (very close to vaporetto stops) and minutes away from many of the main attractions. Leone has done a fantastic job of stylishly designing the apartment to be comfortable for his guests. Despite the small space, we never felt that we were stepping over each other.
Additionally there is a washer and dryer which work very nicely and can help in terms of packing lighter. There is some detergent available as well (we used our own though).
One thing to note is that there is no WiFi but we did have a pocket WiFi that we had rented for the trip so we used that instead.
