I have been on an airline where the flight attendants were responsible for the condition of the restrooms - China Air. Flying coach, I got up to use the restroom mid-flight of my 16 hours. The attendant saw me, raced ahead and did a quick disenfecting and sprucing of the restroom before I went in. It was wonderful, but to be honest I was embarrassed that she did that for me. By the way - the restroom had no odor.
I cannot say I was okay with other practices on that airline - no computers for check in - just clipboards and no calling by section - everyone just crammed forward to board the flight.
