Never rent from strict-policy hosts and your cancellation rate will never be ridiculous. I'm a flexible-policy host.
I'm a consumer and I don't give a hoot about what kind of "policies" AirBnB offers. I've had hosts cancel a week beforehand, without explanation. Thankfully they paid me back, but rebooking was triple the price.
That's literally the reason why I will only book at chains, that can upgrade or shuffle me around their networks at worst.
