Hello @Annabel444 ,
Please do not count on Airbnb to communicate well with guests on your behalf. Expect the contrary.
You should have a scheduled message sent preferably the day before check-in with everything guests need to know, exactly as you want it communicated.
Even more important is a scheduled message the day before checkout explaining how you expect the property to be left, where the bins are, and most importantly why 5 stars is the default expectation and not a reward for an exceptional stay.
Perfect your scheduled messages!
