Thanks. Yes, I'm familiar with the lists. Any room with an exterior door is a dealbreaker, though, and that's most 1* and 2* hotels. I would be very hesitant to book at that level for that reason, mainly.
In my past experience, I've stayed at some high star (3* and up) hotels that had poor reviews, and everything has always been fine. I have only been terribly disappointed with one of my Price.line /Hot.wire wins, and in that case I think it was because the amenities qualified the room as either a 2.5* or 3* (don't remember now), but the quality of the bed and the room itself was 1*. AWFUL. lol. But most of the time I'm very satisfied.
