21y boy looking for accommodation in Madrid

Hey guys, 

I'm going to spend my next academic year in Madrid (Erasmus exchange), so I'm looking for flatmate(s), as it's always easier to find some chill apartment together and good companion is priceless.

Currently, I'm 3rd year law student at Maastricht University (Holland). It would be amazing If I would be able to find an accomodation with a Spanish native speaker(s) as I want to practice my Spanish (it's really basic now), but that's not my core condition, so I'm open for any suggestions. 

I'm a very social person, but with a high respect for privacy. I want to enjoy trurly Spanish erasmus experience, try new things, and meet lots of new people.. so hit me up with any ideas ;)
