【正确答案】Dear Mike,
I am very glad to hear that you will come to China. You can live with me in my home. I live in a 6-story building near Tsinghua University. There is a small park near my home. Once you find the park, you will find my home. It is on the 4th floor.
I live with my parents and my younger sister. My parents both work in a company, and they go to work very early everyday. My sister is an elementary school student.
You can sleep in our spare room during your stay. I think we will have a good time together. And welcome to my home.
