Relocation tips anyone? (London)

Hi!

I will be moving end of February to London from Lugano - Switzerland with my husband. We are currently looking for a one bedroom flat to rent. Preferably close to the Northern Line (work is in Camden). I've targeted N2, N4 and N8 as potential areas to live in - does anybody have any other tips?

Also we are considering hiring Protected content to set up viewing appointments, etc. for us to save time. They earn a months' rent. Anybody else has experience with this company? Are they worth it?

Thanks for all your input!!
