My wife and I recently used Top Santiago, a new company, on the Portuguese Central and they worked quite well. We just let them know every night where we would be the next day. It was 8 euros per transport. From talking to some of the people running lodging along the trail we got the impression they're gaining business fast because easy to work with; in fact, most of them had a supply of the the company's envelopes if guests needed them. Even the nun who checked us in at the Armenteira Monastery said she liked working with Top Santiago.
