@Ang4 I personally would not be interested in dealing nor hosting a person like that. It seems sketchy, or this person is just someone who wants to see what they can get away with. Once you do the reservation outside of airbnb, then pretty much on your own. Which means that if there is any issue later on, you will need to handle it yourself/contact the authority, etc, and cannot ask for help from airbnb. If guests make the cancellation request during the 100% refund period, per new cancellation policy from airbnb, they can get a full refund including service fee for max. of 3 times/year. If I were you, I would direct them to airbnb and they can take care of the cancellation themselves, once it is canceled, I won't be interested in hosting them outside of the system.
