CS is not only a place to stay for a night, it is an opportunity to really know a city. What's better than walking in the city with a local or with advices?? Also, it is a perfect way to make friends. I lived one year in Sevilla, leaving my family and friends and i learnt that you don't have to know a person since a long time to be friend with her. Sometimes ones nights in CS around a good meal are enough.

I can help you with French I really am a bad cook but I can try to teach you some French recipes And most of all, I can share a beer or wine and a good (lets see) conversation
