Lovely spot with a great location.
We spent our days mainly walking around. None of the "things to see in Venice" was far away on foot - and we loved exploring all the various routes, alleyways, bridges and squares between us and the most known spots. Due to the nice location we could always go back quickly and relax a bit in the lovely garden or inside with the air condition if we got tired or too warm.
Everything was clean and neat and the place looks even better than on the pictures. There are even two bathrooms, so staying here with 4 people shouldn't be a problem either (although we were only 2).
Be advised that the garbage collection system in Venice might be different than what you're used to, for example, the garbage collectors will ring your door bell at 8:30 every morning to see if you have anything for them. On the bright side, this allows you to get up early and make full use of your day.
We had a great time and hope to come back to Venice one day.
