Pennsylvania, in the north-east of the USA, is a largely rural and forested state with huge swathes that remain wild and uninhabited. When choosing the best places to stay in Pennsylvania, you can either go deeply rural and stay in a traditional inn, or opt for one of the two main cities of Philadelphia or Pittsburgh which have some fabulous historical buildings, turned hotels.
