Hello @Dävu0,
You will get paid by Airbnb the day after the guests check in. It may then take a few days to appear in your account.
If you are hosting and aren't sure about these things you should read the articles in the help centre.
Especially, type "host" in the help centre and read the atricles. Also, very important, read about "cancellation".
If you are concerned about damage to things in your apartment you should think about adding a security deposit.
the guests are not charged this when they book but it makes it easier for you to claim later if they damage something.
