I booked an apartment months ahead for cheap rent and the host cancelled the booking within 4 weeks, costing me twice the amount to rebook similar bnb. Airbnb did not acknowledge host cancellation policy when I ask them offer the reason of host cancellation which should be beyond their control, otherwise cancellation fees to amend my loss. However, airbnb simply closed the case saying they cannot know why the host cancelled and they would not investigate this, giving the host all freedom to cancel the booking at their pleasure. Please beware when you rent from airbnb, unless your host is nice, the company would not help you or respect their own policy.
