Need advice: damages and over-occupancy

Hey everyone,

I had a big problem with a booking today. The place was trashed, several damages, there were more guests than allowed, and they left late.

I’m a bit lost, it’s my first time having that huge of a problem

When exactly should I notify Airbnb? I don’t have all the invoices and prices yet

What steps should I take to report the damages and how do I price compensation?

Thanks in advance for your advice, I want to handle this the right way.
