@Clara116 Just because we've never run into anyone who hates the smell of something, doesn't mean those aversions don't exist. I'm sure there are some people who don't like the smell of peppermint, even though I've never heard anyone mention that. So I myself would never assume that any scent was universally appreciated. I have a friend who can't stand the smell of coffee. Before I met her, I'd never met anyone in the 45 years of my life before I met her who had that dislike.
I do use some cleaning products that have a scent that I enjoy. But I clean the guest quarters day before check in (no same day or back-to-back bookings for me) and air the room out well afterwards.
I read a hilarious story- a woman had had a nasty divorce after finding out her husband had been cheating on her. Part of the divorce settlement was that he had to buy her out for half the house, then he put it on the market and moved in with his girlfriend. She still had to go and collect the stuff that was hers from the house and went there when it was empty. She took down one of the hollow curtain rods and stuffed some shrimp down inside. Neither her ex, the real estate agent, nor the house inspector could figure out where the horrid smell was coming from and nothing worked to eliminate it. He had to sell the house at a huge loss.
