I normally have guests that stay no longer than 6 nights and usually less than that. However I just had my longest occupancy since joining Airbnb. They arrived 12/1 and stayed until 12/21. Although they were decent guests (2 people), they were pretty messy. It didn't warrant a less than stellar, 5 star review, because they were very good guests in all other facets of their stay. When they checked out, I did a brief walk-thru of the cabin and because it was daytime, I didn't turn on the lights. As a result, I missed the fact that the kitchen counters were covered in sticky food substances, the floor needed to be not just be mopped, but actually needed scrubbing to remove a lot of smears, and the bathroom - suffice to say it needed extra scrubbing too. I wish Airbnb had a way to charge varied cleaning fees contingent on the length of stay. I wondered if anyone had a work-around that would allow me to charge something more appropriate for people staying longer than a week. I typically charge a measly $15 cleaning fee, but that is just fine for short stays. It was definitely not fine for this extended length of time.
