SIM
I bought a couple of SIMs online before my VdlP this year.
Vodafone and Movistar.
My research indicated that Movistar provided the best coverage.
But on arrival in Spain, Vodafone was easier to get started.
So I used that one.
Good coverage all the way.
Hotel
As for Hotels. Hotel Simon is very popular with Pilgrims.
robscamino.com
And a great location! Very Central.
But sadly I did not sleep that well there.
I just got a bad room I think.
Ground floor with lots of plumbing / whooshing / gurgling noises through the night.
But I would use it again, and the staff were great. Very helpful.
