I agree that some people have higher standards than others, which can make for inconsistent reviews for the lower-end places. Last fall I stayed in a mom and pop motel, a typical small mid-century single level place. The room seemed rather dated, like it had last been updated maybe 20 years ago (although it did have a modern flat panel TV and free wifi), the carpet was very worn, and one of the lampshades was torn. Those didn’t really bother me, although I understand others might feel differently. The room still seemed very clean, the bed was comfy, the bathroom looked like it had been redone more recently, the shower worked well. So I was perfectly happy staying there.
