Dear Mr. Smith,
I am LiHua, a student from China. I am writing to express my dissatisfaction with your service.
To begin with, the temperature of the air conditioner in the room is rather too low, which makes the guests catch a cold easily. Moreover, I had trouble falling asleep last night because there was a loud noise in the passage at mid-night. Besides, the guests can not get access to the internet in their rooms.
I appreciate it very much if you could improve these matters, and I would like to have this matter settled by tomorrow afternoon. Thank you for your consideration and I will be looking forward to your reply.
Yours sincerely,
LiHua
