My readings suggest there are human hosts that cancel based upon the high likelihood of undesired guests for reasons not allowed by the platform.
Unless there is a way to guarantee that a full refund is given to the guest (plus 10% for every day before 48-72 hours) I am not interested.
If I was a host - I would like to know that someone would be responsible - apart from "home owners insurance" for any damages resulting from a party.
I personally have never used the service. I do not intend to either because I know at the hotels I do not have to take out the trash or get the last minute cancellation.
For larger groups and families I have used other services where I can communicate directly with the owner. I fail to see the use of a middle-man that has no direct interest beyond service fees.
