This place is really conveniently situated -- it's a short walk from the bus and train stations, and it's easy to take the vaporetto to get anywhere else. The location plus the fact that the apartment is only a floor up really minimizes the distance you'd have to drag any suitcases.
The apartment itself is very nicely appointed -- the bed is comfortable, the toilet works well, there is ample space to relax in the living room, and everything was quite clean when we got there. The kitchen is a little cramped, though, so don't plan on cooking much during your visit.
There's a Conad supermarket close by, as well as a really excellent pasticceria (Pasticceria Rio Marin Venezia) -- we ended up eating breakfast at the latter place every morning of our stay :)
