The WO staff welcomes guests to key in their rooms without checking that the room they are staying at Have you cleaned yet? Upon entering the room, found that the room has been used, there is garbage in the room, the sheets have not been laid, but after informing the post office, it has been changed to change the room. The booking is very convenient, but the hotel staff can't find the history of their stay. Call to coordinate, contact the customer service center to get help. And coordinated very well. Thank you.
