Oh no...
is this definitely an unjustified nasty review ?
If so , and if you are a super host, you should have a direct toll-free number for super hosts .... That's one of the benefits of being a super host . Call to explain the issue . They will check all your other five star reviews and will remove it on your request that it is false. I guess There may be an issue if you have any other bad reviews but I'm assuming you haven't.
Did you leave them a bad review ? The trouble is , if either party does not review in good faith , it makes it hard for all of us. I've now learnt to read every guest's review and if there's one bad negative review , that guest always turns out to be a nightmare ! So becareful.
But remember , as superhosts, we are Airbnb's product and do all the hard work , so make the call ASAP , especially if it's untruthful.
Let me know what happens
All the best
