In the winter of 2018, I studied abroad in Paris, France for 6 weeks as part of the CIEE Open Campus Program. It allowed you to live in 3 different cities over the course of a semester, with 6 weeks in each. I studied in Paris, Madrid and Berlin.
When I chose my arrangement of cities, it was actually Madrid and Berlin that I really wanted to go to. Madrid, because it was the only Spanish speaking city, and I had been studying Spanish in school at that point and wanted to practice. Berlin was because I was interested in Cold War and WW2 history (the former was mostly from playing Call of Duty).
