Single male looking for Flat/Houseshare

Hi, I'm Dan. I'm 33 and looking for a room to rent in Bristol.
I'm signed off paid employment long-term, but work as a volunteer for the Environmental Records Centre, which is part of the city council.
I've lived in Bristol for about 12 years, and in my current residence nearly 8. Unfortunately, the landlord is selling so I need a new place to live, ideally in north/north-west Bristol. Would prefer to have a decent sized amount of personal space and an en-suite but willing to compromise on this.
I will be around the house/flat a lot, but am quiet, clean and tidy and for the most part keep to myself. I don't smoke and would prefer to not be with smokers as I am asthmatic. No pets of my own, but quite happy to live with other people's.
