Just returned from Santiago-Finisterre-Muxia and had to stay in b&b (not municipal albergue) as I was using a bag service.
In Negreira - Albergue Logroso was lovely, you turn off before the town, its a country house run well by brothers with lovely garden and good evening meal. 15 euros - breakfast included but basic.
In Olvieroa - As Pias (which is a nice restaurant) had basic rooms in nearby house, not great value 20 euros each in 2 bed room. you could pay more to stay at the restaurant itself. there was another option there also (sorry don't know the name) other than the albergue.
In Cee, stayed at Das Estrellas, 10 euros. good showers but room is strange shape open plan, bunks, smelled damp, noisy. There is a hotel next door though which is same business. I would try and find something in Corbubion the neighbouring town, which is really pretty. Both these towns are coastal.
In Finesterre, stayed at Do Sol, 12.5 euros in 2 bed room. in a house, basic, bit of a rush on the bathrooms. chilled/hippy, did offer healthy dinner and breakfast.
In Muxia, stayed at waterfront Hotel La Cruz, 25 each in 2 bed room, but nice.
In Santiago, Hotel Gastronomica (35 each 2/bed room) was good, and Hotel Real (40 euros single) also altho bit noisy.
Buen camino!
