24 y/o professional looking for sociable house

Hi, I am a super clean and tidy 24 year old working in London as a trainee psychologist in Pentonville Prison. I'm fun loving and sociable but of course respect others personal space and enjoy my own alone time too. I love going out and exploring new areas and bars but equally enjoy a good film or games night in (I invented my own games night which is known to be a ridiculous but awesome time).
I like going to the gym or and trying out different work out methods (boxing, swimming, dancercise) and would be cool to find a work out buddy in a flatmate. I enjoy going for an adventure in the countryside and mountains.
I'm ideally looking for a big shared house, with a fun group. Even better if there are some musicians in the house and maybe even a cat! A group that is clean and tidy, maybe enjoys cooking meals together and hanging out.
