23 y/o professional looking for sociable house

Hi, I am a super clean and tidy 23 year old moving to London to work as an Associate Psychologist. 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.
