Looking for short-term housing

Hello! I'm seeking a room for the summer, from the mid-June to mid-September. I am a student at the University of Sheffield, and my budget is roughly £400 to £420 per month.

I am tidy and keep to myself, but I do enjoy hanging out with my flatmates too :) It would be great if there's any rooms available close to Sheffield's city centre, although it's not a dealbreaker if it's around 20 to 30 mins away.
