Many thanks for your replies. The Airbnb looks good and I have booked it. I have never stayed in Airbnb before and had trouble with the technology. I had to send my photograph four times before they would accept it, even though it was the same every time!
I walked the Caminho Portugués in September 2014 from Porto do Vila do Conde, then to Rates and along the central route. I had intended a sight-seeing diversion to Braga but this did not work out, so this time I am going to Braga first, and then walking the entire coastal route. In 2014 I had torrential rain for the first 11 days, then a few fine days but heavy rain again on the way out to Fisterre and Muxía. I am hoping for better weather in the spring of 2023!
