Everyone has had that experience where you walk into a hotel room and are instantly put off by the smell.
From musty odors to previous occupants smoking, a smelly room is an uncomfortable place to be.
But just pack a couple dryer sheets in your suitcase and you can easily cope with leftover room smells.
Tape a dryer sheet across the vent of the air conditioner, and the air conditioner will deodorize your room for you.
