I am afraid you might have misunderstood that part of the review policy. Where it states that reviews may not be 'biased', the examples given are:
- Reviews from owners or those affiliated with the listing, 'fake' reviews where you've basically recruited someone to make a booking and leave a review and reviews by direct competitors etc.
- Reviews where extortion has been involved, e.g. when someone threatens to leave a bad review if they don't get XYZ, or when a host gives the guest some kind of financial incentive (bribe) to leave a good review
- Reviews where there has been a 'significant' violation of the party and events policy
So, by 'bias', Airbnb does not mean whether the statements made in the review are true or not.
Quite the opposite. It clearly states in the policy:
"
If you feel a review is untrue
While we encourage and expect all community members to post reviews that contain objective and accurate information, Airbnb doesn’t mediate disputes concerning the truth of reviews. We expect the author of the review to stand behind the content of their review."
That is why Airbnb refused to remove the review. I'm not saying it's fair. I don't think it's fair at all. Your guest basically admits breaking your house rules and bringing additional guests beyond your max occupancy without permission. You have explained well about the security camera and the gate sensor, so hopefully future guests will realise that this guest is making unwarranted assumptions about being 'watched'. It might even be beneficial, i.e. will scare off guests who are planning to try to sneak in extra people.
I am not disagreeing with @Michael5047 's suggestion. Perhaps he has experience of this and has had success, so it's worth a try. I'm just saying that your guest's review does not violate the review policy, so it might be tricky.
