Review scores are also a bit offset. I have tried to give the absolute lowest to every metric booking.com gave me to rate and the resulting score was 2.5-ish. I was thinking about making a browser extension that rescales the values accordingly but I just made a mental note that a score 7 hotel is in fact a score 6. With this scaling the scores on the lower end gain more as a 3.3 score becomes a 5. Take this into account if you opt for the lower-middle end.
