My hotel is very dirty, and then how can I get someone to clean it?

When staying in a hotel, you found the room dirty. You can tell the hotel front desk that the hotel will send a waiter to clean it. However, you should take good care of your personal belongings so as not to lose them. If the hotel won't let others handle it, you can complain. But now the hotel service is still good, and this kind of thing is easy to solve.
