Dear Mr.Li,
I am very happy to hear that you are coming to my home.Now I will show you the way to my home.
I live in the center of the city and it is easy to arrive.You said you lived at XX Street,so if you want to come to my home, first you can take the No.22 bus to he XX Library.You can see a supermarket near the library,and my home is behind the supermarket.
Looking forward to your coming.
Yours,
XX
