20 year old girl looking for roommates for year in madrid

hey im jacquelyn, im coming to stay in madrid for the entire 2017-2018 academic year and im super pumped about it. the one thing i thought would really help me learn the language to its full potential would be living with some girls who are natives of spain or speak fluent spanish! i love to go out and i was hoping to live in the center of the city. some of my friends have gone on the program and say that is the best option! i do have a basic understanding of spanish and can speak it, but i really want to improve upon that more than anything!! i love to go for runs during the day, i also love taking photos and just hanging out. i was hoping for maybe a 2 or 3 bedroom so looking for either 2 or three roommates  or even 4, just whatever works out! here in the states i pay around 550 american dollars for rent and i was hoping to keep my rent in spain in the same price range! let me know if you would like to know anything more about me, i would love to tell!!
