I would consider staying at Yanet's apartment to be by far my favourite airbnb experience.
Firstly the place itself is much nicer in person than in the photos. It is very spacious and clean, and plenty enough for three people. There is both a fan and air-conditioning, so you can sleep comfortably at night.
When we first arrived in Venice, we were late because we had some confusion with the vaporetto, but Yanet was very understanding. Her husband waited for us at the vaporetto stop, and helped with our suitcases and showed us how to walk to the apartment. The location, by the way, is perfect, it's practically a straight walk from the Rialto Mercato stop. And it's also very close to the Rialto stop so you can get around well in Venice.
Yanet and her husband are very welcoming and generous people, she left tomatoes and a cucumber from her garden in the fridge and provided three large water bottles. Their gelato shop is very close and delicious!
Note: there's a Rick Steve's Italy book in her apartment which is useful and fun to read.
