@Rani158 The Air Bnb review system is less than perfect and tends to favour the guest rather than us hosts. Despite a recent new approach about the review being fair and honest, it appears that if you run into a vindictive host, there's really nothing you can do about it except always right a review on the guest that is fair and honest. If you had a problem, there is a box which is Private where you can make your suggestion to the guest. I suspect that Air Bnb have access to that comment you wrote, which you could use as an argument to reestablish your Super Host credentials-in theory. Air Bnb is holding all the cards, so the house always wins.
Another suggestion is to have a minimum age limit, I myself would never rent to high school students.
Good luck and don"t worry too much about the Super Host title that was taken away, work on getting it back.
