guest cancellation 22 hrs after check in

[Leo14]

im confused, my guest checked in yesterday afternoon, they spent all afternoon around town giving my housekeeper time to catch-up, previous guest had a very late check out that same day. Guest got back around 8pm everything was great. This morning again I spoke with them and had no complaints; then at 11am I receive an email cancelling their reservation, more importantly claiming it as a Host Cancellation with a full refund.

Just decline the cancellation by you, he can cancel if he wants to, you do not have to agree.
