Near UCL or bus route 1-2 months

I am looking for a single room or studio in Westminster or Camden from which to commute to UCL, University of London. Either a standard or a weekday let (3 to 5 nights max). Required for 6 months to 4 years. I'm at university all day and return late so it is simply a room for a few hours sleep and a shower. Mature student. No hassle and minimal use of facilities other than bathroom/shower in the morning. Will be away some days of the week.

Also, if 3-5 nights suit you or if you prefer to let for 3 -6 months only please get in touch. Any questions please ask.
