Hi @Evonne17
I am sorry you had such a bad experience. This is not normal guest behaviour. I have been hosting for five years, had hundreds of guests and no-one has every behaved in such an appalling way.
Unfortunately some bad guests deliberately seek out new hosts, because they know they are more likely to get away with bad behaviour.
Can I suggest you remove Instant Book from your listing so you can manually vet guests to make sure they are a good fit before they book until you get more comfortable with understanding red flags and what will make guests a good fit for your place.
I ask my guests a) who is travelling with you b) why did you choose my listing c) what brings you to my city. I also only take guests with photo ID.
Do have a look at Airbnb Help, great for the basics around managing your Airbnb, do look up what to do in the event of guest damage. In your situation I would make a claim for the broken and damaged items. Do take photos and video's.
I agree you shouldn't ask your guests to start the wash as you/your cleaners should be checking them for damage/stains.
If you don't have one already do put together a visitor book covering your house rules, key amenities in your house such as TV, cooker, heating system etc, local attractions, transport, restaurant recommendations. I have a laminated sheet with my check out instructions and house rules on the fridge as a reminder along with key contact details.
