Room near Cambridge station for 10 nights a month

I am looking for a clean and quiet room near Cambridge station for ~10 nights a month, ideally with use of a private or en-suite bathroom. I am a tidy and reliable 47yo professional who travels a lot for work. I also have a main home, this would be a secondary base for work nights. I won’t be around during the day or on weekends so make for a quiet and easy flatmate. Ideal locations would be the Accordia and Caleidoscope developments and adjacent areas.
