Big room with two windows on a little piazza with a bakery. Very quiet. Comfortable bed.
Separate little kitchen and big bathroom. Lots of books on italy, venezia and also novels in English, German and French !
You can easily leave your luggage before check in or after check out.
Be aware that you will have to pay a city tax of 4€/day (max 20€ if you stay several days).
Last thing, if you take the boat at fondamente nuove to the airport, this stop is almost at the end of the line so it is frequent that it arrives full and does not allow you on board… I was allowed on the second boat 30 min after the first one because I was alone and fortunately I had lots of time to catch my plane but this was very stressful… other travelers told me they called a taxi sharing the fare (120€ to the airport but you can be 10 on board!) instead of 15€ per traveler on regular boats. Probably a better option if you are a large party.
