it's a very nice albergue with two small dorms (both have a window), two showers, a full kitchen, and very nice hospitaleros, on a quiet street in the old centre. 5 mins from all services, about 15 mins slow walking from the train station. a bit tricky to find if you are there for the first time cause I didn't see any indications, so use a map or google. it's near the southern part of the old town.
they have info on various routes in bearn which was very valuable to me as I was taking voie de la nive ou de la poste to SJPP (very tricky as the waymarks are sparse and tiny, gps tracks from auceourduchemin site very recommended).
I stayed there twice this year. once on my way to SJPP when I arrived too late to continue on for camino francés (I called in advance to inquire about this and they said ok because there was room) and once when I walked from irún to lourdes.
