Jose was awaiting us with a sign, in the airport building just outside of the exit control area when we arrived.
His vehicle was a very clean van parked just outside the airport arrivals door and he spoke multiple languages, including English, and had us in Sarria quickly and safely. If you go at night, you will miss the scenery, but in about the same time it will take you to get into Santiago and get checked in, you will be in Sarria.

For hotel in Sarria we stayed at Hotel Novoa. Very clean with a restaurant that served breakfast.
Manuel is the father, Juan is the son and Juan speaks English if that helps. Very clean, comfortable and quiet.
Be aware that Hotel Novoa is on top of a hill in the old town area, above the church and painted wall, and the grocery is at the bottom of the hill.
Buen Camino.
