@Emiel1, I get, "Can I cancel the automatic reservation of someone that I think I should not lease to because they do not meet the criteria or I believe they may not follow the house rules or cause problems. Would I get some penalty or something negative?
@Arlette99 , yes, you can cancel the reservation if you are uncomfortable with the guest. The instructions for this are here: https://www.airbnb.ca/help/article/2022/how-do-penaltyfree-cancellations-work-for-instant-book-reser...
If that doesn't automatically switch from airbnb.ca to your own Help centre (airbnb.co?), just search for how to cancel penalty free with instant book.
