Looking for a small single room

I live in Essex but l work in Slough. So l am looking for a tiny room to use 3night a week at most. I will come in after 6pm and leave by 8am in the morning. I will not use your kitchen except for reheating my food in the microwave. I will just come in and sleep, take a shower in the morning and leave. Maximum 3 nights a week, l will not spend more than 3 nights a week. I dont mind rilly, l can even sleep on the couch, l am not looking for much.
