@Glau56 Third party bookings are against Airbnb's terms of service. There is no way I'd accept this booking- contact Airbnb and ask them to cancel it for you without penalty- tell them you don't feel comfortable with it, as she booked for someone else, saying the "have no ability to use Airbnb".
If you take a third party booking and something bad happens, Airbnb won't back you up. These would be complete strangers with no information on file with Airbnb. Would you open your door to some stranger who knocked and just let them stay at your house?
Why would someone not have the ability to use Airbnb? They don't have a credit card? They're under 18? Maybe they had accounts and were banned from the platform. Whatever the reason, it doesn't sound good.
