I'm going to visit Madrid for a week in February with 3of my friends. I don't know so much about Madrid, we're mainly there bacause of the Real-Lazio game. What places should I visit?What experiences shouldn't I miss out on this visit?

That's hard to answer without knowing what your interests are. Most of my--or anyone's--recommended attractions would intrigue some, bore others.
