Short stay for medical internship

I am a 22 years old medical student looking for a room in the center of London (Zone 1), more specifically near Queen Square in Bloomsbury. I am searching for someone available to sublet his/her room for a short period (1 month, whole September from the 1st to the 30th). I am open to share spaces with other people, especially students around my age. I am confortable with basic rooms.
