If you want a clean place to relax and sleep, this hotel is fine. Breakfast was good, and the staff nice. The air conditioner isn't very strong, so it was a struggle to get under 80. When it was new, I'm sure the rooms were beautiful, but they now show the wear of the years. If you want to use the safe, you have to gove a 20 euro deposit for the key.
Location is excellent! If you take the water bus, use the Rialto stop. It's just a 6 minute walk.
