An typical weekday in this program involves grabbing some breakfast or coffee from a café, going to class for a few hours, then hanging out in the city or on the beach for a bit. Spending the afternoon and evening on the beach after class was very popular among my classmates. There's also loads of parks, shops and restaurants to hang out in as well.
In the evening, my friends and I would either cook dinner in our apartment, or go out and try a new restaurant in one of Barcelona's many neighborhoods. Barcelona has great nightlife, so when I wasn't catching up on sleep, I might go to a bar and catch a football (soccer) game, or head down to one of the dance clubs on the beach.
Weekends were frequently spent exploring another city, as it was so cheap and easy to fly out of Barcelona. When I stayed in town, I usually explored a different neighborhood, museum or site in Barcelona with my friends. The hiking in the Bunker Hills is great.
