My exchange in Berlin

This year, my class and me went an exchange in Berlin. We went the days 20 to 27 of may.
My german partner´s name is Michelle and she is 17 years old. She has two sisters, the youger sister is Antonia and she is 13 years old. And the older sister is Chantal, and she is 23 years old. The mother's name is Sophie and the father's name is Isaac.
My class were four days in the families and three days in a hostel.
We visited many things in Berlin, for example: Brandenburger Tor, a house of terror, one day we visited their school, a park, the city in general, film park (it's like a fairground but about films), the Berlin wall and more things...
I liked so much Berlin, I think that is a very interesting city. Although, I didn't like that we had to take the underground/bus/train get to anywhere.
I liked when I was with the family, but I liked more when I was with my class in the hostel, because we were all together and I would pass very well with them.
Now I miss so much the german people and for this, probably I return to Berlin this summer to see Michelle, her family and the german people.
