Hi @Namita0 dealing with a negative review on Airbnb as a host can be challenging, but there are steps you can take to address the situation. Here are tips I can recommend if you wish to dispute your guest's review.
Before initiating a dispute, ensure that the review violates Airbnb's content guidelines. Reviews must be relevant, appropriate, and non-discriminatory. If the review contains falsehoods or violates these policies, you have grounds for a dispute.
Reach out to Airbnb through their help center. Explain your situation and why you believe the review violates their policies. Provide any evidence you have collected. Collect any evidence that supports your claim. This might include messages exchanged with the guest, photographs, or other relevant documentation.
Review disputes can take time as Airbnb needs to investigate the matter thoroughly. During this time, continue to provide excellent service to other guests to improve your overall rating. I hope this helps!
