@Hollie6 I am so sorry that you had this experience with such slobs.
On behalf of hosts everywhere, please do leave a review. You could wait until the very last minute of day 14 to submit your review. As you know, the reviews are "blind" so the guests may give you a stellar review. If not, you always have the option to reply to their retaliatory review.
I would suggest that you take a couple of days to mull it over, then write a concise, factual, and non-emotional review. A detailed review is not required; sometimes "less is more." You could say something like- significant amount of cleaning was required following their departure and they generated more than the average amountof trash.
As for submitting a claim for damages for the mattress pad, that is completely up to you. Maybe in the future, don't buy expensive towels and bedding.
Hope that your future guests are better behaved.
