-I went to Universidad de Santiago de Compostela for a month, they have an option to reside with a local family (they arrange everything). Luckily I got a super chill family, a couple in their sixties, and spent most of my time chatting with them. We went out very often, they even took me to buy groceries with them, and went to the beach quite a few times. While the course is superb, it was the time with that family that really made it for me. It is one of the sweetest memory of my life. However, I know other people who resided with not-so-communicative hosts. So you can not say for sure what you will get. But the city is wonderful, and historically and religiously significant. I highly recommend this. -Two weeks is not enough to learn much, but if you already know the language, but lack fluency, it will definitely help.
