Future Spanish Student from France

Hi guys, to make it clear, I will write this message in English. I'm a French student who lives in Brittany and going to study in the Universidad Pontificia Comillas de Madrid next September. I just wanted to ask if you could help with, I mean, if you've ever been to Madrid or even if you live in, to give me some advice and so on...

Thanks for your help, hoping see you soon.
