Ensuite double required Cranfield area

H,
I am in need of a large(ish) double room preferably ensuite as close to Cranfield as possible. I am a professional full time worker and need somewhere to lay my head at night. I am clean and tidy and am very respectful of other people and their belongings/properties etc. i would be looking for full time lodging NOT Mon-Fri. and i have no maximum length of stay.
I keep myself to myself to the point you would hardly even know i was there. Of course i can be sociable as well. I just fit in to my surroundings.
