My trip to Madrid

When I was a child I went to Madrid with my family because my mother wanted to go and visit her sister so we took the train and after travelling for about twelve hours we arrived in Madrid. I was very excited because I had never been to Madrid before. I was also very pleased because I was going to spend a wonderful time with my father. He worked far away from town so for that reason I spent very little time with him.
When we got to the station in Madrid, my aunt and my cousin were waiting for us and they took us home. My mother's family lived in a small flat in the center of the city so it was very crowded but we could go to many place by foot . We visited the Prado Museum, el Retiro and many more places.
My father has already died but I will always remember those days when I spent wonderful moments with him.

Please I need you correct me. Thanks.
