Yes, you need to write a bad review, but the good news is you’ve already composed it! Just use what you basically wrote above… you are directing it to other hosts. I would not use the word steal or thieves or theft though. Simply describe what the guest did regarding the fridge items matter of factly, and that is enough for all hosts to get the idea. Don’t say complimentary, either because that’s like saying they took all the items we left for guests.
“ xxx guests did not respect check out time, left the house dirty, did not respect our house rules (we’re remote and on hydro-electric power and they left all the lights on), and to top it off, cleaned us out of all items from the fridge and pantry - oils, vinegars, rice, jams, etc. Cannot recommend.”
Now… lastly, and this is very important…wait until the last second to leave the review. The guest probably knows the stay did not go well, and if he gets a notification you have left a review, he might be prompted to leave a bad one for you. So look at the time stamp of the first email notification you got from Air reminding you to review them. The deadline will be exactly 14 days from that time. You can use the countdown timer on the dashboard to watch for it. Have it ready and leave it with like one or two minutes to spare so they don’t have time to leave one for you. Good luck and sorry about the bad guests.
PS… I would also take a look at your house rules and make sure they are firm enough. Sometimes guests sense a newb and know they can take advantage.
