Currently walking the CP central. Municipal albergues are open, but the ones in Spain seem not to have blankets, so you will definitely want a sleeping bag. The going rate is EUR 8. None so far have a washer or dryer, just hand laundry—this is a problem, because clothes washed by hand do not dry in the cold, rainy weather
Stayed in Valenca instead of Tui, so I can’t tell you anything about that albergue. In O Porriño the public albergue was allegedly open, but it was locked and no one answered the door, nor the phone at the other end of the number posted to call. Ended up staying at a private albergue nearby, called Sendasur. For EUR 10 we got heating, blankets, and access to a washer and dryer. It is a newer place, and all the bunks have curtains. Definitely worth the extra EUR 2 in my opinion.
Tried to stay in the private albergue in Arcade, but it was closed for the winter. The manager said it should be open in February, though. It looked nice. Ended up walking all the way to Pontevedra to find the next open place, the municipal albergue. It has good heating but no blankets. The women’s shower did not have hot water, but this might have been a temporary issue. (The men’s shower had hot water.) I really missed having a hot shower at the end of a long day, but the staff was very helpful and friendly, and we did meet several other pilgrims there.
Tonight in Caldas de Reis, where the municipal albergue did not look that nice (reportedly does not have hot water). Ended up staying in a private place, Hospedaje Estrella do Camiño. EUR 15 per person for a bed in a room with three beds, with heating, washer/dryer, and kitchen. The bathroom has a tub, not just a shower, and after walking 37 km yesterday, I would have paid EUR 15 just for the soak in the tub alone! The young woman who checked us in was extremely helpful and gave us all kinds of information about the town. Highly recommended.
Will update more after I get to Santiago (in 2 days!) But generally speaking, there are a few private albergues open in bigger cities, but in the small towns they are closed. For walking in the cold/rainy season, I find that private albergues, when available, are worth the small extra money for the sake of being warm at night and having dry clothes to put on in the morning. Hope this helps!
