Whether you're heading for the Sierras or the costas, historic towns or cosmopolitan cities, this guide has a huge variety of places to choose from. There are simple Casas de Aldea (small traditional houses in remote rural settings), restored monasteries and palaces and modernist buildings with all the contemporary designer trimmings. Stride out on walking holidays in the National Parks, linger by the pool and make the most of some terrific regional and international cooking. Of the 375 properties in this guide, most are under €100 and half have rooms for two at under €70 per night.
