Double room in laid back flat share

My flatmate is leaving the start of December and looking to replace him with someone easy going and good natured.
The flat is a ground floor flat with nice neighbours upstairs and very nice students on either side.
The room is a decent size, situated at the front of the property onto Gloucester road with my room at the back and a living room and kitchen between. A spacious garden is entered via the living room and is the ideal spot for a morning cuppa.
I am a very easy going professional man in his mid 30s who enjoys socialising and good conversation but understands the importance of space. I enjoy board games, video games, movies, reading, the gym, going out to the pub - all the usual things. Ideally would be good to find someone who I can get along with in a friendly capacity.
I am transparent and upfront, so any questions feel free to ask. Bills work out around £200 with council tax etc. So the total with rent would be roughly £800. There is also a damage/safety deposit upon securing the tenancy which is £538.
I hope all this makes sense.
