Our hostel in Sevilla was in the old town, and Sevilla's Santa Justa train station was a bit outside the center. It would have been a 45-minute walk. So we took our first and only taxi of the trip, via this entirely-civilized taxi queue. Supposedly, Sevilla plans to extend its little tram, which runs into the old town, out to Santa Justa, but this project keeps getting delayed, so who knows.
