First, all the things that we really liked. There were 4 of us, 2 couples in their 60s-70. We were here 2 nights. This was originally a 1-bedroom apartment with a large living room. The living room was made into a 2nd bedroom with a king-size bed; includes a dresser but no closet or any place to hang clothes. The other bedroom has 2 twin beds next to each other, large closet and a dresser. Living room has couch and TV, but now a great place to hang out, so we hung out in the kitchen.
The Positives:
Bedrooms are quite spacious.
Only 1 bathroom but quite large and light. Excellent shower. Love having a bidet.
Kitchen is comfortable with a large table for hanging out.
Washing machine in the bathroom. We'd been traveling for 3 weeks and really needed to wash some clothes.
The Negatives:
We did not understand at the beginning that there was an agency handling the rental. They were business like in a negative way--not trusting, wanted a $200 security deposit for 2 days stay because people who are 60+ could easily damage the place. They did not supply laundry soap because we were told people might steal it.
Description does not say it is on the 2nd floor, 32 steps up, a lot for me. I didn't go up and down often.

There are rat traps on every stair landing and we could hear rats between the walls, though none in the apartment. Perhaps this is true throughout Venice, I don't know. I would have liked it had they told us, and said none are in the rooms. On the ground floor near the door, part of the wall is torn out and not fixed. Could rats get in and out there? Why not fix it?
They were very strict about check out time--10am.
Most hotels are friendlier and more accommodating.
They are VERY expensive, but we were stuck because I had accidentally canceled the place we were supposed to stay so this was a last minute option.
My kids host Airbnb travelers and we have all stayed with Airbnb hosts. The best are those who live in the house and rent out 1 or 2 bedrooms which is how Airbnb was originally designed. The best are those who host from a place of generosity and trust, who want to make it as great an experience as possible. The best are those who I hope will visit me and let me host them because we've had such a good time.
My kids supply some food and drink, are generous with washing machines and dryers, offer suggestions about things to do, places to visit, restaurant tips. They try to get to know them and their situation a bit.
Bottom line, I would not stay here again.
