I only had 2 issues with this AirBnb, everything else was nice.
First issue was a lack of pictures which made it a bit misleading. There are 5 or 6 rooms in this AirBnb which are not all the same. The lovely bathroom pictured was not what we received, but rather a MUCH smaller and more cramped bathroom, in which there was barely enough room to move while in the shower (you can see this bathroom walls in the corner of some of the bedroom pictures) The bathroom also had a large opening in the wall, meaning light and sound travel to the bedroom very easily, so depending on who you are with and your relationship with them, milage may vary 😅
My second issue was location. I will say it was nice and close to the train station which is good. We got a bus to the area which also stopped at the train station so either way you arrive it is a short walk. Trains into Venice are frequent and cheap. BUT, even so, i think if i were to return i would rather stay inside the main island. Price is similar enough, and for the convenience of being able to pop back to your accommodation without having to get a train or bring a backpack for your bits. The walk from the station to this AirBnb, while only about 5 minutes, is also not great at night. Not terrible, just a bit uneasy.
Everything else was fine, so if those 2 issues don't bother you, this is a nice place to stay, especially if you want to explore the area not just on Venice island. But i think If the price is similar enough you should stay on the main island:)
