Student searching for Room from September

My budget is 750/800 £ possibly and my move-in date is quite flexible, possibly around mid september but it can also be later.
Preferred areas would be:
- russel square
- king’s cross
- islington
- fitztrovia
- mile end
- stratford
- hackney
- bethnal green
- shoreditch
- hammersmith
- stamford brook
Just as an indication, but open also to others: I would need something student-friendly, easily commutable to UCL (Bloomsbury).

I'm Paolo, soon to be MA student in UCL, starting September. I'm 23, my course will be halfway between political science and philosophy and I'm looking for a place to rent. I'm from Rome and, as a basic Italian, I like to cook and enjoy company around the house, obviously keeping into account different routines. I'm now quite used to living with people: I took a gap year and had quite a variety of accomodations, between NGOs, Brussels and Kenya.
Thanks!
Paolo
