LOOKING FOR ROOM IN CENTRAL MADRID

Hey everyone! I'm a 22 year old English teacher from Scotland looking for a room around the centre of Madrid. I'm an easy going person, and I'd really like to live with Spanish people in order to improve my Spanish. My budget is around 400€ and I'm looking to move in as soon a possible. If you have a spare room/know anybody that does, please email me: jamienolan93@hotmail.co.uk
