23 year old Swiss student looking for flatmates near/in the centre of Madrid

I'm a swiss student doing my master degree at the UC3M (Puerta de Toledo campus) and I'm looking for someone to share an apartment with. I found multiple big and modern flats near the centre and would love to share the costs and also have a good time with the person/people in the aparment. I work part-time and would therefore aim for a 1'500-1'900 apartment (for two people) or 2'000-2'800 (for three people). I'm a very chill, tidy and social person but I know how give someone their space and privacy. Feel free to reach out to me if you're interested!
