Sorry to read this.
I hope you have reported them to. Authorities to follow up on.
If you use related keywords someone may have put a suggestion in CC.
Alternatively try slicing an onion in half and leave it in the room to absorb the smell, it works for paint.
Baking soda sprinkled on carpet and mattress and left for a few hours or if possible overnight may help eliminate it.
If you have net curtains they are easy to wash oneself however other curtains where the smell is also absorbed will need cleaning.
Very annoying problem to rectify Have you contacted Airbnb support to lodge a claim for related expenses?
All the best
