It's unfortunate that this happened, but I am not sure that you will be successful with your refund request due the statement, "Access is easy", because the implication is that it's easy to reach in a vehicle that's not carrying/towing additional cargo. By not disclosing this to the host, it is a bit of the pot calling the kettle black when you accuse the host of omitting information that could impact your access to the cabin. When I looked at the primary photo, it was obvious to me that from its viewpoint one would have to go up a steep hill to reach the cabin. Also, the reviews date from this past winter, and there was at least one that mention poor weather, but none of them state anything about difficulty reaching the cabin.
Normally, I would inquire if you have travel insurance, but in this situation, I am again unsure if a claim would be honored for travel disruption.
