Sporty/laid back 30yr old Male Professional

I'm a 30 year-old male, currently living undesirably with my parents in Newport (its only been 2 months). I have done several house shares over the span of 8 years or so, so I'd like to say I'd make a harmonious house mate. I'm looking for a double room leaning more towards the centre of Cardiff, and ideally, I would love to share with like-minded young professionals/mature students (maximum of 4/5 tenants). May also consider a buddy up. I am a highly active person (Gym, run, and cycle), love music and I am always keen to socialise. I also do enjoy a bit of quiet solitude.
Budget is 550-650pcm
Require a parking spot
Outdoor area a bonus :)
