London

The postcode drops you right in the thick of Belgravia, where cream-coloured stucco terraces line tree-shaded squares and the money is old and quiet. This is London at its most polished - think diplomatic residences, private gardens you can glimpse through railings, and the sort of shops where they don't display prices.

Walking these streets feels like stepping into a period drama. The architecture hasn't changed much since the 1820s, when the Grosvenor estate carved up marshland into what became one of London's most exclusive neighbourhoods. Eaton Square stretches grandly eastward, while Chester Square offers a more intimate feel with its central garden.

From here, you're a proper stroll from Buckingham Palace and Victoria Station connects you to everywhere. The Thames is close enough for riverside walks, and Hyde Park Corner puts you at the edge of one of London's great green lungs. Westminster Cathedral's red-brick Byzantine tower looms nearby - completely different from the Abbey everyone expects.

Staying at one of the holiday parks on London's edge makes brilliant sense for exploring central spots like this. Lee Valley Camping and Caravan Park in Edmonton or Chessington World of Adventures Resort give you proper beds and green space after days tramping round the capital. The contrast couldn't be sharper - from Belgravia's urban elegance to countryside camping in a single Tube journey.

Honestly, SW1W is London showing off. But it's the real thing, not a tourist version.
