Ermanno was really an ideal host. He met me and walked me to the apartment, noting that it can be hard to find on your own. He undersold the bathroom (which was amazing-- such a lovely shower head!) and the views -- a canal is literally outside your window.
I couldn't work the locks at one point, and he came down to fix things for me. He also let me keep my stuff in a storage locker on my last day, so that I didn't have to worry about lugging it across Venice. When I got sick and missed my flight, he offered to call me a doctor (despite having already checked out) and double-checked that the next renters were going to show up, so that otherwise I could stay another night. He gave great tips for uncommon sites to see and overall was a wonderful host. I cannot recommend him highly enough.
The apartment definitely smells like the canal, aka a tiny bit sulphuric at times, so if you're sensitive to that, I'd keep the windows shut, but otherwise, what a great place to stay.
