I keep it short and only ask my guests to pick up after themselves. I ask that they leave the beds and not to take apart. It allows me to check for stains before I wash the sheets etc.
I basically have everything in my guidebook already and then either refer for example pet waste or damage and make sure basic items like garage door remotes and keys are placed back in the zippered envelope they found it in and to place on the kitchen table or counter. Make it as simple as possible!
