Sevilla
Do not miss the old town including the cathedral and the Giralda, the Alcazar, the barrio santa cruz, plaza de toros, the tower of gold. Outside of the old town plaza de Espana and if football fans go to a lot Pizjuan stadium.
The alcazar is worth a couple of hours, also climbed on the bell tower of the Giralda, the landscape is very belllo (typical Andalusian).
Already in March when I went I was hot (30 °).
