Where to begin. I cannot rave enough about my experience in Malaga. I loved absolutely everything about it, from ISAs friendly and helpful staff to long afternoons spent on the beach, sunbathing and eating gelato. The climate is perfect: warm and sunny, and it barely ever rains (at least in the fall). The host family I lived with was absolutely phenomenal - even though they didn't speak any English, they were kind and understanding, and living with them helped me improve my Spanish by leaps and bounds. A normal day consisted of going to Spanish class for a few hours, and one or two classes later in the day. I usually went home to eat lunch with my host family (which gave me great access to the local cuisine,) and would spend the rest of the afternoon either on the beach or hanging out with friends. Because of the airport, train, and bus stations in Malaga, it's very easy to travel, nationally or internationally.
Essentially, I loved everything about the ISA program in Malaga. I would go back in a heartbeat if I could, and treasure every memory I have from my phenomenal semester.
