Is the hotel ranked from good to bad? What is it, five stars, three stars? Which is better?

The hotel is divided into two stars, namely, two stars, three stars, four stars and five stars. Five stars is the highest level at present. Of course, Dubai Sailing Hotel calls itself a seven-star hotel because it thinks it is more luxurious than a five-star hotel, but according to internationally recognized standards, there is no such thing as a seven-star hotel. Beyond the five-star service level, it can be considered as super five-star, but there is no such level in the standard.
