I suggest you adjust your weekly/monthly discount rate to factor in weekly cleans - for instance, a quick vacuum of floors, check and provide new towels, check soap/shampoo, change bed sheets. It's important to explain clearly to the guest what your weekly clean includes so they don't expect you to be cleaning up their messes 🙂 Also, it's a way to keep an eye on the place and make sure problems don't fester.
I once had a guest forget about a couple oranges she had bought..... which had started getting moldy in a plastic bag in a corner of the room hidden behind some books. Henry took a picture, send it to the guest informing her we would throw it away, wipe all surfaces, change all the sheets, and spray disinfectant in the room to make sure there weren't any stray spores. The guest appologized several times but as hosts we were just glad we found it before it caused any serious issues or became a major health hazzard.
