Professional Male seeking double Room, Bristol

I am a professional male aged 27 looking for an unfurnished double room with enough space to fit a king-size double bed and my computer desk in. I will be moving back to Bristol after a 6 month secondment and would like to find a place in the south of Bristol commutable to the rail lines as I work in Abbey Wood.

About me:
I'm 27, British and I work for the MOD in Cyber Security on the engineering grad scheme. I am coming to the end of the scheme and potentially changing jobs to the centre of Bristol, so would like accommodation nearby with easy train access.

I'm a very chilled guy and big on PC gaming and spend a lot of time playing and relaxing on my PC, but I'm also pretty social and always willing for a night out or chatting/hanging out. I am also big going to the gym and always happy to have a gym buddy. Not much of a sports person, but have a bit of an interest in rugby union, otherwise I don't watch/play much. I rate myself as a fairly decent cook and like to cook a nice meal every now and then. I'm fairly tidy - my room is can be a bit messy with clothes, but I always like to keep all communal areas tidy.
