Hotel guests reported that the room hygiene was particularly poor. How do you reply?

First of all, we should understand the specific problems reflected by the guests, such as dirty towels and linen, dusty walls and furniture, and dirty cups. In any case, these will help us find the problem. First of all, we should sincerely apologize to the guests and thank them for their questions. Secondly, measures should be taken, such as rectifying the room immediately, or changing rooms, or even giving some compensation.
