It is a wonderful albergue. I dont think the hospitarelo is there all the time, ask at the end bar opposite the doors of the famous church. I think they are relations and will phone for you. Its a big place O.S.M. a lot bigger than I thought - the walk to the albergue is also long.
I have really enjoyed the Aragones, i am surprised how busy it has been. I did the detour to Pena and made Arres the same day from Jaca. The detour is only worth it if you really want 2 go, there are no buses. If I wanted to see it, the best option is to walk to santa cilla de jaca and stay there. There is a path not far from there.
There are lots of river walks, beautiful plants and lots of vultures and eagles. Highlights have been the stay at Arres. I arrived after 8.30 and was treated like a king (there are dutch hospiterelos who are there for 2 weeks and are an amazing couple who will given you there shirt) That night there was no bed I was in the overflow (25people there) in the chapel on lilos, but the numbers can very last sunday the albergue had no pilgrims.
Staying in the priests house (ask at the church) in Accous (france) was a highlight - very kind, very nice meal (lots of veg) and very friendly priest. I know its a big walk from o.s.m but worth it.
Tonight I am in Sanguesa and the albergue is full despite arriving at about 3pm - That pension in the csj guide has also closed down. I am staying in the camping place near by and its worth considering if you get caught like me as there is a variety of accomadation (there are thick mattresses and duvets) and free internet hence this mail but its 18 euros. Hopefully 2moz I see the bathing raptures - i am so looking forward to it. Any questions about anything, please pm me and I will tell you what I know. There are some places when you need to carry lots of water and food as there is a stretch when you pass no village (Arres to Ruesta), I have been drinking river water but had diarahh twice!! So i have learned my leason.
