London is the dirtiest and most expensive European city according to a survey of well-travelled tourists.
This is a scandalous slur! Can there be no tourists who have used London's superbly reliable and inexpensive underground system to get to the London Borough of Waltham Forest? Arrive at Walthamstow, toil up 47 steps (because the likes of us ain't worth buying an escalator for) and stroll through these spotless streets to the William Morris Gallery.
And find it closed.
But not to worry. You can always go for a stroll in the adjacent park.
