We really struggled to find a home in Venice without stairs which would accommodate our family of five, preferably be minimum bridges away from land - to accomodate a wheelchair. Alberto's home was perfect choice for us as its stair-free and very close to the main train station (only one small bridge).
His instructions to navigate to, and check in are crystal clear (complete annotated photos). His communication was prompt and he made sure to message all our alternate numbers at all times.
The home is tastefully decorated and clean. Its actually cuter in person than in photos. (But the coffee mugs were all very dirty, perhaps a function of guests having to do the dishes themselves before checking out).
There was no air conditioning though listing said there was. So it got really hot at night. Upstairs does not have any window except skylight and I could not figure a way to get fresh air in without mosquitoes.
The living room sofa bed was broken. He had someone try to prop it up - with books - the next day but it was too late, and we had already booked a hotel for part of the family to sleep for day 2. For this inconvenience - Alberto waived the 4 Euros per person tourist tax he had asked us to leave as cash upon checkout (not mentioned in the charges on the listing, even though its what hotels in the area charge). But two of slept on the floor first night and the hotel we had to book for second night last minute cost us $380.
I am not a seasoned Airbnb guest yet. After my Rome and Venice experience, I think I would stick to hotels when traveling with extended family, especially seniors and young children so I know exactly what I am getting and don't feel guilty/obliged demanding my money's worth. I would still try Airbnb when traveling alone or without friends/partner. And also carry a sleeping bag, just in case.
