Looking for a room

Hi,
I am pretty new to the London and looking for a room.
Currently I am working for a Online casino as Customer support, and working from home for mostly on a late shift (2pm - 11pm) basically, but if you prefer me to, I can work from the office some days a week as well.

I am looking for a double bed room, internet, washing machine, kitchen, and some storage space, but pretty open up for other offers.
If bills included, that's great.

Is there any nice and reasonable price of room to rent around?
Please let me know:)
