Maurizio & Francesca's place is stunning and the bedroom we stayed in was spacious and the whole place was immaculately clean.
The location is superb! My wife and I really really enjoyed it. The directions were perfect and we found the place easily.
The only thing we would found a little awkward was that the bathroom, (although private to us), was found by walking through the common dinning/lounge area. There are also (understandably) security cameras in that same hallway so my wife was very aware of the fact if she was coming back to the room from a shower or using the washroom in the middle of the night, the owners were probably getting motion alerts. It wasn't a huge deal but it was just something to be aware of.
We didn't interact with the hosts as this is more of hotel style run place. We only saw the owner as we were checking out as she was there cleaning up the rooms and we simply said goodbye.
We would stay here again without any hesitation. We think the value and all the things we appreciate like cleanliness and location, were met.
Enjoy your Venice travels!
