International Student short-length stay

Hello, I am a Brazilian medical student who is going to undergo a one-month research internship at the University of Cambridge. I will need the room mostly just to spend the night and mostly through Monday to Friday (in the weekends I intend to visit London and other British cities).
I don't have many room requirements, I actually just need someplace with Wi-Fi, a Laundry-Machine and a Kitchen that I could use.

Please let me know if you need any further information :)
