Maurizia and her husband were perfect hosts. The space is very private, in a good location, was very clean and tidy, and I was escorted to the location - which was wonderful, considering it was my first time in Venice.
A few things to note: wifi is not available, only a 4G hotspot, so make sure to ask for the key and password, and access is limited to a few hours a day. It worked for me just fine.
The beds and shower are very small. I am a small person so this didn't affect me at all, but if you are taller than perhaps 5'6 or so, your head might hit the top of the shower ceiling!
Other than these two things (which, again, were no problem, just for good round feedback), I would highly recommend the space.
