Something like that happened with a property we purchased (early bad review on Airbnb from a construction related situation out of our control). It was terrible. We had already refunded them their money due to the issue but still got a bad review.
Here's what we did. My wife called up the guest and politely asked them if they'd be willing to remove the review because the negative review would make it challenging for us to run the Airbnb going forward.
By some miracle, the guest agreed to remove the review! A few days after the issue took place, they weren't mad about it anymore and they didn't want to do long term harm to our business.
The only way for the review to be removed is for the guest to call up support and explain the situation and why they'd like to remove the review.
Anyhow, it's kind of a longshot, but it worked in our case. We ended up sending the guest a holiday gift basket to thank them for their understanding.
