Going to Berlin through greenheart was an amazing experience for me. There were a lot of people from a lot of different places, so I got to meet people from all over the world. In my room, we were one Turkish, two Belarussians and a Francoamerican - and that’s only our room. German classes were good although I think I should have been more militant about them putting me in the right class - if you go, make sure to be on their backs about that. The rooms were fine, we just didn’t have space to put away our clothes. The staff was really nice, and we got to do a lot of activities, with a lot of free time every day. Overall, I think this experience is totally worth it, especially if you find people who are willing to only speak german with you.
