My husband will be joining me on the last 100 km of the Camino from Sarria. His best option is to fly from Madrid to Santiago, the get to Sarria. I've seen posts regarding taxi service (Ivar's?) from Santiago to Sarria. Can anyone shed any light on this....how difficult is it, can we reserve ahead, etc? He isn't real keen on not having things lined up (not a "seat of the pants" guy at all). Any help would be appreciated.
