Translation :
Hello my friend,
I am sending you this letter from Guatemala. I came to visit my cousin Roberto, who lives in Antigua, Guatemala. Roberto is seventeen years old. Antigua has many old buildings. There are small and large houses. Yesterday I went to Tikal. Tikal is an ancient city of the Mayan civilization. Tikal has more than sixteen square kilometers. I hope you like the photos.
Regards,
Xavier Yahir
Hope this helps!
