The AC-Heating unit in my room was cleaned and now has the freshest air I've ever seen in a motel. Most places have units that smell musty and will make you sick, but not at the Motel 6! The toxins from molds can make one's joints ache and their sinuses hurt, but after a few days I feel good all over. I'm so glad that Motel 6 pays attention to what most motels think are ”little things,” but are very important: environmental health through clean air. A vacation in a ”sick” building can never be good for anyone! Thank-you Motel 6!
