@Barbara174 - actually that's a great start to writing a bad review. They are hard. The key is to keep is short, sweet, and factual. In your post you've given some good details where my review might look like this: "Communication was good up until check in, after that communication broke down. After booking last minute, (x, y, and z) were in and out of the house frequently and then checked out early without talking to us. They left the room in disarray having moved furniture around and left wet towels on the floor. They also left dirty dishes in the sink. We would not host XX again and cannot recommend her to other hosts."
They give them a thumbs down, mark them down for communication and house rules to minimize their ability to instant book with other hosts. If they did other good things, make mention of those too - just keep the "feelings" bit out of the review.
Good luck. If you get a bad review from her, respond with a few short, factual sentances that include saying you are sorry they were unhappy (because you are - you're not a monster). There are lots of great tips from hosts in the forums about how to do this.
