Agree cleanliness is paramount. I can do all the gardening and sorting out of toyroom, or ensure the tv remotes all work etc, but if there is something not cleaned, the guests penalise harshly. Sigh.
The one thing that always catches me out is the pots and pans, or the plates. Previous guests dont clean properly for whatever reason, and we don't empty all the drawers to check them all (there's like 24 plates/24 bowls, 15 pots/pans ) because this is a 12 guest 6 bedroom home. It would take an hour just to check them all, pulling them all out and checking.
I know some guests will just let it go and accept that's part of the holiday house, but others will get very picky on it and rate me down. Never mind that this is easily fixable.
Just part of hosting life!
