Whyyyy do so many Airbnbs have STRONG air freshener and scented sheets?

Like the title says… why? I hate strong synthetic smells and I LOATHE sleeping in a pillow that makes me feel like a cloud of perfume is around my head.

We’ve stayed in 5 Airbnbs over the past two weeks, and only one didn’t have one of these offenses. I even told one host that I was allergic to fragrance, and the little automatic smelly squirt thingies were still in place and turned on… after she assured me the place was allergy free.
