Simple - put it in the review. 'Broke house rules and did not follow check out instructions' and dock a star. Honest review.
You are new - this is going to happen again. Most of my guests follow the rules and check out instructions. A very few don't.
To help them - I have the check out instructions (Which are simple and as I tell them - it helps to keep the cleaning fee low) posted in MULTIPLE places. On the fridge and in the unit guide and the back of the door.
For the house rules that are MOST important to me - E.g. not smoking cigarettes or weed - that I found were broken sometimes - I put a FRAMED notice very prominently - saying 'if you smoke weed, I will smell it (i live upstairs) and you will be asked to leave' Since I put up this notice, it has never been broken! Win!
I also put some handy notices in plastic 'notice stands' around the apartment with tips for check out .. Very friendly and nicely worded. Has really helped.
Often guests are just oblivious - they don't read the guide so you have to help them out a bit with them noticing what you want them to do.
Good luck!
