i visited the taberna miami in mid june this year out of curiosity, having read that they supplied an interesting credencial. the owner is an amusing
fellow who will happily show you photos on the wall of him doing a camino on a horse. i asked about acquiring a credencial and he laughed saying they hadn't done this for years - so don't count on it unless someone can verify they got one there recently. but it only took a couple of minutes to pick one up at the cathedral, no charge. there are any number of affordable hotels in seville. getting out of town proved more difficult than i had hoped as i was looking for shells on walls. there are a few shells from the cathedral until the other side of the triana bridge where you hang a right. then forget about shells other than a couple on the pavement which you could easily walk over without noticing.
take the first set of wide steps to the right climbing about 5m up an embankment, cross a busy junction diagonally, and then it's yellow arrows all the way to santiago. i wasted an hour in the small hours scouring walls for shells which weren't there.
