everything was great! the location is central, easy to get everywhere, vaporetto stop in 2 minutes away. There is 1 big room with a bed and 1 smaller room with a sofa bed but very comfortable (we were afraid about the quality and the dimensions of the bed but we didn't even notice that if was a sofa, it was comfortable and big - my boyfriend has 1,93m and it was a good fit for him). Perfect for 4 people. The guest welcomed us with a gift too, which was really nice.
The only thing I recommend is to better explain how to get to the location - we arrived in the night and not being used with the narrow streets of venice, we searched a little bit for the location because we didn't know that gangways are also streets. But once you get used, it is very simple :)
