Well, first, their heating and ventilation ought to work, and be on the quiet side. It would help if the hotel / motel would not be so cheapskate that they completely shut off that unit as soon as the room becomes available, lol. No residual or active bad odors would also help. A clean room, good securely fitting substantial door and windows that close and lock properly, non-threatening neighbors, and a building that looks like it has decent wiring that won't burn down overnight and meets safety codes: All of those are required, too I just had to say that for the Big 5 or 6, haha, because I can think of some memorable bad rooms that I encountered back when I traveled for business.
Second, I'd wager that most of the major chains are using a tried and true Bonnell or possibly Lura-Flex spring with some plush padding on top. If the bed feels rock hard, I'd wager that it's a Bonnell spring with not much foam on it. But over the past 10 years or so, the typical beds have gotten softer and I think it's due to added foam layers on top of the same traditional innersprings. Luxury hotels might use some other spring system, perhaps a pocket coil. I am just guessing, based on my experience.
