Looking for a room in Battersea or North London

I'm looking for a single or double room in London to rent for a minimum of 6 months to 1 year.

I'm full-time professional based in North London and I am looking to move to a new role which is based in Battersea. I'll prioritse areas with good connections to Battersea, though I'd also consider moving to quiet/leafy areas of North London such Crouch End, Highgate, or Hampstead. I'm looking for a quiet and bright room with lots of natural light and good sense of space. I'd appreciate a flatmate who is respectful and values when the shared spaces are kept clean and tidy. Having access to the garden would be nice.
