@Kirsty-And-Jason0
Kirsty....or Jason, get in touch with a company called 'Sharecover' they work specifically with the Airbnb and the Homeaway/Stayz platforms.
I am not recommending them as such.....anyone will take your premium, but it is what happens come claim time that sorts out the 'wheat from the chaff'!
I specifically don't get involved in insurance recommendations any more because it is like walking on quicksand....the rules are changing all the time and whenever I have opened my mouth here I have ended up eating my words.
Google Sharecover and see what they will do for you! That's all I can say!
Cheers.....Rob
