Beautiful and modern hotel, helpful staffs, excellent location near Hightech Park MRT station, International Expo (SINEC).

I booked for 2 guest in business room with breakfast included. But then the hotel charged 1 person breakfast fee for 158CNY/night. How come they give free breakfast only for 1 person and the other person need to pay? When I do the booking, there are 2 option between the no breakfast room and room with breakfast. I chose to pay more for the room with breakfast. then still have to pay more on the hotel for 1 person breakfast?
