In September 2004 we stayed in a good hotel in Seville. It was close to all the recommended sight seeing spots, we could walk to everything we wanted to see. It is called the Hotel Cervantes. http://www.hotel-cervantes.com/ Select your language flag! It has a garage which we didn't need as we arrived in Seville by train. It says it has rooms from EUR 50, I think we paid more than that but it was a very big room. The people are nice and the breakfast was good. I wouldn't want a front room because although the streets are very narrow they are cobbled and any cars are noisy. We walked about at night - one has to to find a restaurant, and we didn't feel nervous. In fact we had to ask directions back to our hotel and the person we asked was a Canadian!

Good luck, Margaret in Melbourne, Australia
