in the comments section on this article, was this. This makes me pleased that I can offer a fragrance free listing. Too many hosts do not understand the serious problems that fragrances cause. Aside from bothering guests, fragrances are quite often made of toxic chemicals, which the manufacturers are not legally required to disclose.
I've (mostly) stopped staying in Airbnb due to fragrance allergies. American hotels wash bedding and towels in fragrance-free detergent. Not so of most Airbnb places I've stayed in. I even ask ahead of time, but what that has meant every time is the host will wash everything in fragrance-free before we get there, but you can still smell the fragrance from all of the previous washes (it takes many, many washes for that stuff to come off). Once I was assured they always wash with fragrance free detergent, but that was definitely not true. Only in Iceland was our Airbnb truly fragrance-free. I eventually gave up on it, and now we book hotels whenever we can afford it. Hotels at least know that to accommodate everyone, you have to go fragrance-free (I wish they would do this for body care products, but that's okay, it's easy enough to travel with my own).
