There are many poor ones and many good ones, but it's a matter of where you are going. The brands also matter, as I like many of the IC properties, especially the IC SF, but there are good HI's like the HI Golden Gate, both in San Francisco. I'd had good experiences with the HIX properties, especially San Clemente where I stay frequently, and even a Candlewood Suites in Jacksonville, FL, but I have moderate expectations about them. On the other hand, the worst HI stay I had was a HI in NYC that made me wait 5 hours to get me into their worst room, facing the back, view of the building across an alley. And they seemed to enjoy pissing me off, as they checked in other guests who arrived after me.

Asian IHG properties seem to be the best.
