Dear sir or madam,
I am a customer who has visited your hotel last week. I'm writing this letter to tell you about my experience and to hopefully get you to change a few things.
To begin with, it seems that my room did not have a TV or a computer, and I often watch TV at 7 every evening. I would assume that a TV and a computer are basic appliances, and the rude steward and stewardess who are reluctant to answer your questions didn't make my experience more enjoyable. One thing that I would love to see changed is the infrastructure of the hotel to appeal to the customers. Also, the stewardess and steward should receive weekly training to improve their service. I would greatly appreciate you taking my advice into consideration, and I hope you can take measures to improve your hotel. I look forward to hearing from you soon.
I hope this helps!!
