Seville

Not to be missed: the historic centre with the cathedral and the Giralda, the Alcázar, the Barrio Santa Cruz, the bullring, the Torre del Oro. Outside the old town there's the Plaza de España, and if you're a football fan, go to a match at the Pizjuán stadium. The Alcázar deserves a couple of hours, and do climb the Giralda bell tower too — the view is very beautiful (typically Andalusian). Already in March, when I went, it was hot (30°).
