Hello @Amber979
On your IB setting, have you enabled the "good track button"?
Only allow guests who have stayed on Airbnb without incidents or negative reviews.
Knowing that Guests reviews are rounded up rather than down like with Hosts, this 3.5 guest doesn't sound great. It takes a lot for a guests star review to be brought down so tread carefully.
Let us know!
All the best
Joëlle
