You have 29 listings and the two that say "new" still have instant book turned on. As a professional broker, you need to be hyper vigilant when it comes to handling the ins and outs of Airbnb. It's interesting that I cannot find any bookings for either of those properties on their calendars - so which listing are you concerned about?

With 29 listings at your disposal, you probably have space for this guest to move to another location.
If not, as an IB user, you do have some benefits for cancellations if they meet the criteria for exception. You can look all of this up in the Help Center and if you want to contact Airbnb, use the "search for anything..." box above and utilize the community help guide to contacting Airbnb before you cancel the guest.
