Dear Mr. Jefferson:
I am writing to thank you for your kindness and hospitality I enjoyed during my stay in your place.
It is very kind of you to invite me to spend my Christmas holiday in your palace last month. The room you arranged for me in your house was quiet, clean and comfortable. The food was very delicious. And visits to local scenic spots were really wonderful. They have not only broadened my horizon, but also enriched my experience. By the way, if it is convenient for you, please come over and spend your Spring Festival this year in my place.
Thank you very much again.
