looking for a single room near UoB

I am 53 year old, new PhD student at UoB and this is my first time to UK. I am from Palestine and work as a freelance consultant in scial development. I will be travelling to UK alone during the study Period. I prefer to have a single bed and room shared with maximum 3 students. During my stay I may have online tasks (part of my consultancy work) to perform, therefore it is prefered to have quite environment.
