HEY! HAVE YOU EVER LIVED IN SPAIN?

I will be studying in Granada for 5 months. I leave in less than a week. If you have ever lived in Spain, do you have any tips or suggestions?
  1. Background info: I'm a Spanish minor, so I know a good bit of the language, though I'm certainly not fluent. I will be living with an older couple who will be my host parents. I have read several guidebooks and travel websites, and I feel like there's not much more I can learn as an outsider. However, nothing beats a local's advice.
