@Christine2783 Her offer to "try to get AirBnB to refund" is deceptive. Any refund, whatever amount, is entirely up to her. It sounds like she has not been entirely gracious about all this.
I hope all of your messaging has been through AirBnB. If you are still not comfortable, you can reach out to AirBnB and ask to be relocated. I'm not sure what area you're in and how much short term rentals are in demand, so that could be a limiting factor.
Her "fresh scent" comment indicates that she's pretty oblivious to the fact that not all people are on board with that. There are those that have become so accustomed to "that" via highly successful marketing, but again- she's in the hospitality industry and is catering to a large, mixed market, and has to adjust her personal preferences to suit those who are coming to her accommodation.
She could mention in her listing that she uses strongly scented laundry products or sprays, and give guests the option to request their bedding be laundered in "free and clear" detergent before their stay (although those strong scents tend to hang on through multiples washes.) She could even have separate sheet and bedding sets.
Anyway, you should be comfortable where you are staying, and if you're not, you are within your rights to ask for a change, if you feel that the host has not handled your concerns responsibly. Good luck
