I booked a hotel room for a few days on Booking.com. It was rated 3 stars. It was a hell-hole. It smelled of mold; the AC didn't work and the door wouldn't lock. After seeing the disgusting room. I asked for a refund from the hotel and got all but one night refunded. Later, Booking.com sent an email asking for a review of the hotel. Then I realized why it was rated 3 stars. Booking.com doesn't allow you to rate any lower than 2.5 stars, which they round up to 3 stars. This is UNEQUIVOCALLY DISHONEST. I am certain I am not the first, nor the last, to be scammed by them. I'm sure they are being paid a fee by these awful hotels. They are not representing the consumer. There are many other ways to find discount hotel rooms. Don't use Booking.com.
