Hello,traveldog3,
We share an interest. I too am looking for a quiet village with good bus lines available and near a train station, preferably in Northern Spain. I believe I have found it in Aviles, Asturias. I have a few cousins that live there and after looking at the housing market in other areas, I've found that Aviles is the town for me.
I searched "google" for housing prices in several towns, and found that Asturias is a very resonable area to either lease, buy or build a small 2 bdr/2bath cottage or piso.
My questions now center around the type of visa I will need to live there without being hassled. Let me know what you find. Good luck on your search!
Carmen
