NWL <850 pounds incl bills.

Why moving: I currently working at Hillingdon hospital, and have been living close. Unfortunatly it's out in the sticks and I'd like to live slightly closer to central london (where everything is) to stop me going stir crazy. I'm looking for a new one, but require something half way between current job + future job.

About: I'm laid back, I don't particularly drink or party. I keep to myself mostly but by no means anti-social,
I don't smoke and I barely drink. I don't own any pets.
I clean up after myself, respectful etc etc. The bare minimum you would expect, you know?

Requirements:
-Budget : <850pm (including bills).
-Household: < 5-person.
-Somewhere decently close to a tube, or near activity.
-Parking: required (Stubborn northerner refuses to let go of car)
-Room size: Enough for a desk setup + extra so I don't go mad.
-Roomates: Nice :) some cool flatmates to get along with and occasionally go to gigs etc with would be a bonus!
-Live out landlords only, please.
