Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it's packed then The Red Lion is just up the road.

This is one of the only platforms on the London Underground that is not bombarded with billboard advertising. It's a reminder to myself of how an uncluttered environment can give you so much more room to think.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

Regeneration or gentrification? Having been living in and around Brixton for almost two decades, I'm not the only one witnessing its gradual transformation. Right now, Brixton offers an intriguing mix of Jamaican and British culture like nowhere else.

My No.1 favourite graveyard in London. Calming, overgrown and a little bit spooky :)
