@Jen-And-Mike0 Unfortunately I had a similar situation where I had Airbnb terminate a stay 3 hours in due to breaking a house rule. That person was also allowed to leave a review (but thankfully he did not!)
I'd make sure to leave a professional response to his review and make sure you mention the stay being terminated and why (so other guests will then understand why they left a retaliatory review).
Airbnb allows any guest to leave a review if they've checked in and spent time at the rental to allow them to share their experience. I know it does not make sense for a guest who was asked to leave - but I don't think they will change that.
