I wondered if AirBnB had considered using a rating other than stars? I feel many guests seem to get confused with 5 star hotel ratings when they are reviewing. I have an older home that I rent out, and I clearly state that it is partly renovated and that the furniture is older, but guests who say they loved the place often still give really low ratings for cleanliness because the furniture has some marks or wear etc. I wondered about a heart rating or thumbs up etc, so as not to be confused with hotels.
Also when your reviewing a guest and the question about if they had discussed any problems with you. How do you answer that when you haven't seen their review and often don't find out about their problem till they put it in the review that you can't see until after you have answered the question.
