The place is very pretty and looks just like the pictures. It's very close to rialto bridge which was convenient. The walls are very thin, however, so you have to be very quiet at night and could also hear everyone outside and any neighbors. It's also more comfortable to sleep on the sofa bed as a sofa rather than making it a bed, as it's a bit old and creaky.
The toilet did not flush very well sometimes, and the bathroom sink also did not have cold water (the kitchen sink and shower were fine though). Like other reviews said, the airbnb itself was quite cold at night. It was fine to sleep in though, since the blankets were quite thick, but walking around was a little uncomfortable. I messaged the owner about these complaints, and she did not really address them.
There were no amenities provided, including hand soap, so we had to go out and buy some. The owner compensated us accordingly, however.
