Англичане, пожалуйста помогите исправить ошибки в письме)

Dear Sir,
I admire your hotel. I have been to your city for the first time and I was amazed by the beauty and grandeur of your hotel. When i got in there, I felt a warm and pleasant atmosphere. I was pleasantly served, the employee told me the story of the city: about the architectural attractions and places of interest, and also about the date of the establishment of this hotel.
I liked my room. It was well tidied, bright and beautifully decorated. I rested in your city very well, but circumstances have forced me to immediately return home. I was late for the plane and when i came into the cabin, I realized that I forgot my little bag in the hotel. There was a very important paper left in the bag, which I need for work.
Please, could you tell me how can I get my bag back? I need to visit you or you can somehow deliver it to my place?

Вроде всё остальное нормально.
Удачи
