Hi Pomeng,
I'm Xuan from Asturias in the north of Spain. Ago more time I traveled by bike Prepirineos and Camino de Santiago, before I did anothers travels by bike, China, Inner Mongolia, India, Nepal...you can see my travels in my blog xuandeisla.blogspot.com.
If I don't travel in June, you could contact with me, and I could give you couch. I live a few kilometers of "Camino del Norte"(It's a variant of "Camino de Santiago"). In a few weeks I´ll travel by bike with my friends, we'll do "Camino del Norte", is another variant of "Camino de Santiago", but I think is more beautifull, is less transited, there're less turist and nice landscape. You can see this way here http://caminodesantiago.consumer.es/los-caminos-de-santiago/del-norte/ when I finish, I can tell you about this way
