There are times in which the host agrees that the guest desire to cancel is acceptable to the host. The host is wanting the guest to feel good about Air BNB and does not want the guest to be penalized. However, currently Air BNB contacts the host on behalf of the guest asking if the host agrees with the cancellation. Trying to be understanding, the host agrees to the cancellation and is then subject to penalties of host cancellation. The dates are blocked. Why would this be the outcome of a mutual agreement between guest and host? I suggest Air BNB to either not penalize the host for the cancellation or at very least warn the host that agreeing to the guest cancellation results in the dates being blocked.
