First, ewwww. Second, perhaps use this as a reason to rethink some of your systems. I wouldn’t leave anything in a shared space that I wasn’t ok with a guest using/touching. Get a tote and remove your items as needed?
not all guests arrive with courtesy nor sense, best to limit what damage they are capable of. @Erin205
and, my review would mention their inability to stay out of host’s personal belongings so don’t recommend them for shared space listings.
And, btw, I’m more offended by the rifling through of drawers than the use of a freebie toothbrush. The first is rude no matter how you look at it, the second could be see as an available amenity (depending on its location of course)
