@Kelly149 since your original question was whether I personally would be uncomfortable with this IB, I would say: not to the point of cancelling the reservation.
I would communicate with the guest and make it clear what guests are normally asked to do upon departure.
I would let them know that I wanted their stay to be 5-star and that my goal would be also to have a great experience hosting them so that I could give them a terrific review.
You and the guest both want the trip to go smoothly and to be able to leave flattering reviews of each other.
Try to let them know you are both on the same team with the same goals, and try to work out how you can both make that happen.
People often live up or down to your expectations of them. If you go into this assuming they are going to be disaster, that often brings the disaster.
And (while it doesn't happen all the time), letting someone know that you believe they can be terrific often gives them the chance to be the terrific person you are hoping for.
(Background: I did a lot of youth work and found this to be true for teenagers.)
Let them know you are going to give them a chance, and also work to help them succeed.
Most people are capable of being great guests; help this one be a great guest and they may surprise you.
XXXXX and her band stayed while they were on tour. Communication with her was very easy and the entire group was exceedingly polite. Betsy said this was her first time using airbnb and I feel that perhaps there was a lack of understanding on the house rules which were posted on the wall. The place was left in fine condition for a hotel, but not nearly as tidy as most guests leave it. Trash was on the floor, dishes left dirty in the sink, garbage not taken out as asked for in the house rules, all the towels had makeup stains on them, and things were not put away after use. While I enjoyed her group personally, it did take more time to clean up after them. I would be more clear on the rules the next time.
