@Arran0 For the review, you could say that unfortunately the guest didn't comply with some of our house rules, such as taking proper care of the furniture and fireplace, which required extensive cleaning. (Gets the point across without being too emotional.)
Also, less is more--especially for the important stuff. You might find that guests just won't read an overly detailed house manual. (I say this without seeing it, I realize, so no offense. I just find that repeating the top 3 rules always works best.)
The person who booked is the representative for the whole group. So even though that person may not have been the actual person who did x y or z, they're the responsible party.
What do you think?
