23 year old girl, looking for room mates and accommodation in Madrid

Hello! My name is Ruby, I live in Brussels, I am 23 years old. I am an outgoing person, I love travelling, going on adventures and discovering new things. I also love music, dancing and meeting new people.
I’ll be going to Madrid for my Erasmus Exchange at Complutense (Somosaguas Campus) on the 1st of September 2018 until the 30th of January 2019 (4 months). 
I am looking for a room in a shared apartment in Madrid in the centre (for example in Plaza de España, close to metro line 3 which leads quite easily to la Complutense). 
I am also looking for cool female roommates who would like to share this experience and an apartment with me, if you are also going to attend la Complutense as well that would be a great plus but it does not really matter :)
