Hi @Benjamin777 , your fears are realised. I suspect you will need to create individual accounts.
The Airbnb platform isn't designed for Hotels, so while you find it another way to reach customers, you probably have to accept the administrative downside but it's free advertising.
BTW, have a look at the account with the Blue kitchenette; it shows '0' beds.
And, I was wondering why you are encouraging people to jump on the furniture?
Cheers, Charles
