No, you’re not wrong.
You should leave things ‘tidy’, meaning things are in their original place and trash and recycling are put away rather than left as litter throughout.
A ‘1’ on cleanliness per Airbnb review standards means “not at all clean”.
I would respond to the Host’s review to say:
“Host’s review did not conform to Airbnb guidelines. A ‘1’ means ‘not at all clean’ and yet we complied with Host’s checkout instructions. We started dishwasher, stripped linens, cleaned kitchen and swept. We did everything on our checkout instructions and it was very tidy. Paid $300 cleaning fee. Unfair review. Do not recommend.”
