Fancy shacking up in a 17th Century mansion for a week? Gran Hotel Son Net is, to put it frankly, completely lush. Think grand suites, beautiful decor, marbled bathrooms. The surrounding area of Puigpunyent is beautifully green, but you can shut out the sun by hiring a poolside cabana for an afternoon snooze. One last thing to entice your fancy self: you can hire the hotel's plane for a trip to the Guggenheim in Bilbao. In high season, a suite will set you back nearly a grand, but go a little off season and you can bag a garden view room for as little as £170 per night.
