Best Hotels in Long Khanh, Vietnam

I have stayed at the hotel and would like to rate the hotel with a few ideas, the hotel is clean and airy. However, the host is not familiar with when guests book the application on the app, specifically when arriving at the hotel, they force the guest to open the application back and forth, take a picture of the reservation code. Not yet, when checking out, make the customer continue to open the application, open transaction information and invoices on the customer's personal email.
