A postcard-worthy Victorian B&B in Notting Hill between Hyde Park and Portobello Road
Perhaps the nicest B&B in London—though not the most central (in Hammersmith and Fulham)
Harrods of London installed a novelty in 1898: the world's first true escalator (to be fair, an inclined moving belt with metal bars for traction did make its debut two years earlier on Coney Island). The oddness of a moving staircase so unnerved many shoppers that employees were stationed near it with smelling salts and cognac to help revive those overcome with fear.
