Rude staff, filthy rooms, stinky, loud guests
I checked out the night before and ended up staying in another hotel. 
I just got off the phone with the Crestwood front desk--they refuse to refund me for the 2nd night because I didn't put enough of a fuss.
Oh well! It's not enough money to even waste my time. I'm happy to just give them a poor review and move on with my life.
Hint to hotel staff: You're in CUSTOMER SERVICE. Act like it or get a job in a different field.
