I am with you on this, and unfortunately there are hosts who love them. Personally, I am in love with fresh air from an open window, and perfumed things like this make my body totally miserable. As a guest, I suggest that you ask your hosts to remove any of these that may be in place, and air out the place before you arrive. It is what I do. We may not be able to change the world, but we can ask for clean air in the places we live and sleep in, as guests.
