23 old girl looking for accommodation or room to rent or share in Madrid, preferably near alcobendas or la moralejas

Hi, my name is Sara and I am a 23 year old teacher student who will conduct my internship in Madrid at a Scandinavian school for six weeks between March 23 to May 3. I am therefore looking for somewhere to stay during these weeks and I am looking for a small apartment or a room to rent. I could also concider to live with someone else who needs someone to share an apartment with.
