Even hotels costing well over $100 per night can be a bit ratty. What gets me though is that in most major cities, for a $300 room, the only real difference is found in the hotel lobby. The rooms are barely any nicer than hotels costing half as much.
One of my worst experiences was in a Hampton Inn. They had a new chef who used old shrimp in the salad... Boy was I sick!
Many years ago, while on a very strict budget, I stayed at what looked like a very nice but inexpensive motel in a rather seedy part of town. The first thing that I noticed was the unusually large selection of adult movies. I mean the guest book thingy listed dozens of dirty movies. WTF, thought I. Later that evening, I noticed that a rather large number of very nice cars were parked in the parking lot. Then I started to notice the color scheme of the motel - soft pastels.
I finally realized that I would be the only person in that motel sleeping alone that night.
