Staying in an air bnb in Europe. Lovely house, but contains all the owners things in a way I haven't encountered before eg food left in fridge/ freezer, clothes in cupboards, toys on shelves, medication in low down drawers etc. There's room for our things so not too much of a problem, but it wasn't mentioned in the listing (I'd assumed it was a holiday home as other air bnb places I've stayed haven't had this). It's a new rental so no prior reviews. It was expensive but is quite swish (pool, nice furniture etc) - I feel like we've broken in!
Aibu to use some of the things eg shampoo left in the shower, oil in the kitchen? It's hard to keep dc away from lego and nerf guns in easy reach in their rooms!
