Are there any six-star hotels?

Analysis:

Well, the hotel's star rating ranges from 1 to 5 stars, but the usual 6 stars are an image description of the hotel's grade according to the star rating standard. For example, the Grand Hyatt Shanghai is a five-star hotel, but its luxury exceeds the average five-star hotel, so we say it has reached the "six-star" standard. Another example is Burts Hotel in Dubai, United Arab Emirates, the most luxurious hotel in the world. We say that its star rating is gone. "

For example, many hotels are quasi-five-star, that is to say, they are not officially rated as five-star, but the level can reach five-star, which may be in the evaluation or something, which is very image.
