Excellent place to stay and a terrific location. Three things to note:
A. The location is terrific. Getting there is easy, you can use the San Silvestro vaporetto stop and don't need to cross any bridges. This is a big plus even if your bags have wheels. The local restaurant choice is very good. But on thing that's terrific is that a good local food market (Coop) is only about 50 yards away from the front door. If you plan to buy/make meals this is a major plus.
B. The stairs are narrow - this is typical for Europe in an old city so should not be a surprise - but you should just know that.
C. The kitchen has a stove-top and microwave but no oven. Again, not an issue as it's described correctly - but you might miss it in the right up.
We were extremely happy with our stay and would highly recommend staying here as long as you can manage stairs.
