I've heard many reports that the Case Verde in Hotel de Orbigo is wonderful; I missed it on my first go.
My daily expenses on Camino averaged to 27 euros, but I did splurge in Astorga to deal with leg injuries and checked into the Via de la Plata spa hotel there -- if you find that you have terrible shin splits, their special ice-cold/hot immersion basins for the legs were amazing. Also, if you stay with them, there are 2 or 3 places in the square that they own and you take your hotel ticket with you to acquire a pilgrim supper (or at least that was the case when I stayed in 2014). I intend to treat my dear Spouse to a night there this year as he will have come all the way from SJPDP and I am merely meeting him mid-way this time.
I stayed in a Cast Rural 2 villages below O' Cebreiro on the day of the descent from there. That was very nice (they had *heat*, and I and my walking companion had come down with colds).
The parochial in Astorga was difficult. The hospitaleros were lovely, but the dorms were very crowded and we were actually subjected to a couple making out in a bunk in the middle of the room. And for whatever reason, the youth (presumably) felt a need to draw penises all over the doors in the WC's. Kitchen facilities were pretty barren. But it was also only 5 euros and I still needed rest and time for my walking companion to catch up, so....
We found the municipale in Vega de la Valcarce was clean and comfortable and a lovely pair of young women from Brussels decided to cook for all of us which was nice. There's a funny/quaint al fresco dining/kitchen area.
Make what you can of these little notes.
