23 years old student looking for a room in a shared flat, Madrid

Hola!

My name is Ruggero and I will move to Madrid in September, to study at Universidad Complutense de Madrid for a semester.
I come from Italy but I'm currently studying in Belgium. 

I am a sociable, quite and respectful person, who is willing to discover the city.
I am looking for a flat to share with other people (2-5 persons), preferably spanish people so I can practice and improve my spanish :)
I'm searching for an apartment near the city center or in a place where it is easy to park my car (free parkings).

I have a preference for flats where overnight guests are welcome, as I would like to invite my mother/sister for a few days!

I hope to find someone great to live with and, above all, to make new friends! 
Bye! 

Ruggero
