Your town (London)

Hi everyone!

I'm working as a travel manager and I need to prepare a little report for my collegues regarding London, it's life, interesting events, places, hotels, restaurants, streets, parks and squares.

I have two questions:
1. What is your favorite place in London?
2. What is the most important in London's Genius Loci?

Waiting for any advices as the theme of my report is very difficult for me. London is too big and there is a lot of information but I can't understand what i should to tell:)
