I walked from Lescar to Santiago in 2016. I spent the first night at Lacommande. It wasn't exactly by choice, as I'd hoped to get to Oloron. However, there was a narrow path after Artiguelouve signposted through some trees that ended up at a broad track with no obvious way straight on (apparently a T-junction) and no arrows. I turned right and ended up in Arbus. I asked for directions and was sent back to the T junction. Fortunately I met a cyclist who knew the area and he told me to carry straight on from where I'd emerged from the narrow path onto the broad track. Hidden among the bushes and trees on the side of the broad track at what I'd thought was a T-junction, I found a narrow track which was the way I needed to go. As I had wasted several hours being lost, I was not able to reach Oloron that night. The auberge in Lacommande is next to the church. It is very well appointed. I hope you have better luck than I did!
