I was next to the elevator. I asked to move. They said no. I had industrial machinery banging on the other side of the wall.
There was someone else's hair on my blanked.
I came into my room. The air conditioner wasn't on. The front desk man said it would be on shortly. When it was still off 15 minutes later, I began looking for a new hotel, and then checked out.
It wasn't one thing. It was all of them. The air conditioner was just the last straw.
Also, overall the place - my room especially - feels shabby. And my bed was small, way too low, and narrow. Plus, by the time I left - about 1PM - my bed still hadn't been made.
