I always read guests’ reviews, and sometimes check out the person who reviewed them, especially if all reviews use similar wording.
If they kept to the rules and arrangements, didn’t cause any damage but weren’t the tidiest, then I’d focus on the positive. If you’re overly critical, it could impact future bookings. That said, I always score as I find and state if they were messy on the private feedback for Airbnb.
It’s swings and roundabouts, some guests are spotless, some are not. I pay my cleaner the same weather she does a 2 hour clean or 4, as the cleaning fees go to her. Though, if it’s above 4 hour’s, I obviously pay the extra. I only charge for 3 hour’s, as the extra is for windows, checking cutlery and crockery etc, which is my responsibility.
Some people are just not as clean as others, or are in a rush, or are having a bad day on checkout. Most people are on holiday, so I don’t expect too much.
The worse thing is causing damage and not telling me, as it’s hard to pinpoint the culprit if you have a few back to back guests.
