Looking for short-term room

I am PhD candidate in English linguistics and I will be staying in Manchester for a little over a month for my PhD. I already spent 4 months in Manchester about a year and a half ago and loved the city, so I am back!
I am looking for a room from the end of May until late June/early July. I am a very respectful and tidy roommate, so I excpect the same (I am not a neat freak though!).
I am a bit of an introvert, you can usually find me working from home or in the library. I enjoy taking dance classes, reading, and going to the cinema or theatre.
I would love to find a place for just the time I will be in Manchester, but I am willing to pay for extra weeks (during which I will be back in Italy) if needed.
