If the guest says the room has not been cleaned for five days, what should the hotel front desk do?

In two cases, one is that the facts have not been washed away. Apologize to the guests first, and AM will greet them and make corresponding compensation. Secondly, find the reason from the housekeeping department to prevent this from happening again. The other is that guests make trouble, which is a sign that guests want to attract the attention of the hotel (though excessive). Then they should pay due attention to the mood of the guests, greet them through AM, and send them greetings and small gifts.
