Looking for a place to live from September

Hi, 

I am currently looking for a place to live. I am going to be a first year male student at UCL (main campus) so any place close would be very much appreciated. I do not have any preferences concerning gender or number of people living there. My budget is up to £850 a month, yet I may be able to pay a little more for a nice flat in a nice location. It can even be a shared room. I am able to move in already on the 16th September. 

Thank you
