The Daily Wildcat is a great newspaper produced by UA Journalism students. It's worth following (also, if you can, donating to keep the lights on and the presses rolling). The September 30 article Hotel McCoy: An art space and a place to stay, by Sohi Kang and Bellah Nelson, is a long and interesting read with plenty of photos.
This blog has lots of photos of the hotel's murals. You can see them all by searching for posts labeled "Hotel McCoy" (click there).
