Parochial: church based / owned. The Albergue Sao Joao i.e. is a really vast convent.
In average I spent 27€ per day (8-15€ for the night, 3-5€ for breakfast (try to avoid the tourist traps) and the rest on dinner or drinks and fruits).
Ate only on 2 occasions in the Albergue. In Esposende, where all Pilgrims cooked Pasta romana (2 italian pilgrims prepared the main dish, I met them the day before in Vila do Conde) and in the Albergue Portela, where the Hospitalero prepared a vegetarian meal for all pilgrims.
You could go cheaper, but my budget was not as limited like in 2019, as I walked the CF.
As mentioned in this thread: Porto is indeed a wonderful, charming city, not too expensive. I stayed there for 3 extra relaxing days after returning from SdC (beach, bars and sundowns) and spent ~190€ for ***Hotel, Transportation, Activities, a bit of shopping and food/drinks in these 3 days.
Hope you have a wonderful experience on you Camino.
