A room or studio please

Hello all,
I will arrive in Madrid on April 7th to teach. I will stay until June 29th. 
I am looking for a studio or a room in a quiet, clean apartment with responsible non-smoking people, ideally sharing the flat with one only.
I am mature, clean, quiet, responsible and easy-going.
Can you help me find a room in central Madrid for around 11 weeks?
