In reality, all you need to provide is a clean place for the guest!
Some good tips are to make sure you have good towels and bedsheets, and also to always have a good supply of toiletries available (toilet paper, soap, shampoo, conditiones, etc...) for the guest's use.
We always have little extras around the house (mayo, mustard, ketchup, coffee, sugar, creamers, olive oil, etc.) and I let them know they are available for their use in my welcome message.
Try to stay in contact with your guest to make sure they don't have any issues/questions/needs...and let them know that if there is anything that is not up to your listing standards, they can to let you know right away...they have to let you know in order to give you a chance to fix it.
Some people do not say anything to their host during their stay, but then give them a bad review for something that could have been fixed.
