Sorry to hear what has happened to you, it's not the norm as you well know,
My first question, did you take photo's to back up your claim?
Only I had a guest some years ago saying the property was nothing like what he booked, complete B/S that day I had let my cleaner check him in, Right I'll be there in 5 minutes with my ipad,
I proved him wrong.
In defense of airbnb how can they approve every listing? They have to rely on the host being honest, I have seen similar post to yours in the past, I thought what could they do to improve that,
With my car insurance I have to download an app and do a walk around my car before they renew my insurance, if thats possible I dont know.
I agree with you airbnb should have acted quicker and give you your refund, I did think they were supposed to find you alternative accommodation? maybe Im wrong..
