Getting around was a pain in the ass. I wish we'd had bikes! Seville is beautiful, but more expensive than Madrid and Barcelona, in our opinion. The cathedral and bell tower were lovely, and the gardens of Alcazar are a can't miss! We loved all the beautiful orange trees that lined the streets. Don't eat them though! Great food, probably the best we had in Spain.
Insider Tip:For food: Le Petite Comite and La Brunilda are wonderful, but a little pricey. Rent bikes. I wish we had!
