In addition to the original booking fee, after checking out of the hotel, I found that there were some charges, I did not know what those charges included, and did not mention them when I checked in, so I did not enjoy any extra services, it is a pity. Later, I re-viewed the app for booking, and in addition to the last step of payment, the following lines mentioned the money, but I was not clear what the specific purpose was. The hotel has since refunded the money, which I am glad to see and hope to mention such charges and services in an obvious place. All the best and a happy New Year.
