Living with a host family was one of the most rewarding experiences of my Study Abroad. With my family, my Spanish improved, I learned more about the Costa Rican culture, and most importantly I was able to make life long connections with Costa Ricans.
It was cool to see how much your Spanish skills improve simply by using it everyday with your host family, friends, professors, etc. It's frustrating at first when you can't get out exactly what you'd like to say, but with time, patience and lots of practice your Spanish improves drastically.
I learned more about myself than anything else in the program. I learned about other cultures, people, different ways of life, the list goes on, but i learned so much about what I think about all of these different and new aspects of the world. It was very eye-opening.
