My advice is to goto the front desk and ask to speak to a manager.
I've got upper respitory problems, and part of our request is that no air freshners, etc are to be used in the room, cause headaches etc.
Well, we goto teh room, they sprayed air freshner, my dh called the front desk, and said, we'll have a manager call you back.
Then I remembered what people said here, when you call its a not the actual front desk, but a call center, i wasn't going to wait in a room making me sick,
Headed to the front desk, spoke to a manager, did have to wait to get a new room, but no offending odors in the new room.
