Hi Nicole, sorry to hear what you went through but this is not the right place. Host Voice is meant for things like feature requests and suggestions to improve the platform. But since we are here, this what you do:
1. Calm down, you have 60 days to make claims.
2. Document everything. Take lots of photos and keep all your repair and cleanup receipts.
3. Request money from the guest with the evidence you collected, if they ignore it for more than 72 hours Airbnb will get involved.
4. Leave a bad review for the guest in question, and maybe warn hosts in your area by contacting them directly.
5. Think about changes you can make to protect yourself in the future. We've had people lose the keys a number of times, but we have spare keys and copying them was like $3.
6. Focus on your next guests, better ones are coming.
