A friend recently was stranded in the Swedish capital on her way north due to an airline strike. In a panic she asked my advice on where to stay in Stockholm. "What a lovely place to be stranded!" I replied. And it's true: Stockholm surely has some of the loveliest cityscapes, history, architecture, shopping and dining in the whole of Europe, not to mention a choice of fine Scandinavian hotels when it comes to putting your head on a designer pillow at night.
