Not sure what type of listing you have Lesya. Mine is two bedroom house and the “house notes” are a 2 page document that goes over everything guests need to know:
Wifi password and what to do if internet slows, care of the grill, fireplace care, expectations of child supervision, reporting damage immediately, and many other things. This is completely different than my “house rules” on Air. A lot of it really overlaps, but on Air I only list the important things.
I always send guest a copy of the house notes and departure checklist before arrival. If they book me through VRBO, etc. or directly then I send them this info along with a contract to have signed and returned. Once I receive the contract, then I will issue an invoice for payment.
My “house notes” are lamenated and are in a brochure holder on the wall. I tell guests there is no need to print the info and let them know where they can find it upon arrival.
