25 y/o Young professional looking for a room

I'm a 25 y/o public sector auditor looking for a room on a long term basis anytime from late February to June.
Anywhere in North London near Finsbury Park, Clissold Park or Blackhorse Road, or in South London around Battersea, Oval, Kenington or Camberwell would be ideal.

I'm looking to share with other laid back, sociable, similar people keen on friendly conversation and good food.

I tend to spend my weekends on climbing trips, cycling, catching up with friends over park walks or gallery trips, playing board games and cooking and baking lots of vegetarian food.

I don't smoke regularly, and would like to live with people who don't smoke inside. Pets are great and I don't have any of my own.
