As this is the hosts mistake, you should not have cancelled yourself !
The host should have cancelled and you would have full refund.
Or you should have contacted Airbnb and ask them to cancel.
If the communication about amenities not available is recorded in the Airbnb message system, you can still file a claim at Airbnb. But be prepared for long waiting times a Customer Service.
BTW Did you communicate with the host about any refund ?
