Motel 6, Mishawaka, Indiana. The Worst US Hotel
Let me quote the author of the photos: These pics were taken at 3AM on a rainy night in Sept. 2013. Checked in after a 15-hour drive and was greeted with the grossest room ever. Left after 40 minutes to pitch a tent in the rain, and have not received a refund or any satisfactory action. Will never again trust Motel 6, and will make sure as many people as possible see these photos.
