From «Notting Hill» (1999) on Portobello Road to «Harry Potter» at King's Cross (platform 9¾) and Leadenhall Market as Diagon Alley, few cities are this cinematic.
The London Underground, opened in 1863, is the world's oldest — fondly known as «the Tube».
Quiet spot: Leake Street, a legal graffiti tunnel under Waterloo. With a data eSIM, Citymapper and Google Maps guide you through the Tube, contactless rides stay easy and you skip the dead ends underground.
