I'd add the nuance that you can end up with a pretty crappy experience at a 3+ star chain hotel for whatever reason. Usually though it's something that doesn't matter all that much at the end of the day like a room with minimal natural light.

But generally speaking midrange business hotels are utterly unexciting--which is to say they're predictable which is what I'm looking for from my hotel in general when I travel. I'm probably not there for the hotel experience.
