While you can post public replies to Airbnb reviews (within 30 days of when the guest left the review), Airbnb doesn’t allow you to remove them. However, they would consider taking down reviews that you report for violating their review policy. These include reviews that:
include profanity, name calling, or assumptions about a person’s personality or character
mention a person’s religious, social, or political views
are based on circumstances out of anyone’s control, such as weather
are based on non-Airbnb services, such as restaurants, airlines, or rideshares
