If you're looking for a place to stay in Basque country that's off the beaten path, I recommend Estepan's place. It's clean, spacious and offers a beautiful view. The apartment was also nicely stocked with some essentials for our trip.
I would bring earplugs if you're a light sleeper. Because it is so quiet in the countryside, you can others moving around in another part of the house, dogs barking, etc.
