This house is adorable three story home with two just slightly smaller than normal size rooms. But it is Venice so space will be limited no matter where you are. I would definitely recommend as there are many pros to the house. It is the perfect size for 2-4 adults and a very comfortable living space. The house is in an easy to find, quiet area and is conveniently located next to the Arsenale water bus stop.
A few caveats to consider: the water metro is very expensive for tourists so you pretty much have to walk everywhere, and the house is a good 1/2 walk to the main city center and nightlife. There is no oven, regular or toaster, in the kitchen so it makes cooking for yourself difficult. Lastly, the 2-in-1 washer/dryer is VERY VERY noisy and takes like 4 hours to do a wash/dry cycle. It also dries your clothes with steam or something so they come out really wrinkly/linty.
All things considered, this place is really awesome and cozy. Paolo was really accommodating and responsive, and we loved staying there while in Venice.
