When my son and I reached Los Arcos in the early evening after a 40km day, we found that there was no room in the inn ... any inn or alburgue
Well, the Camino provided in the form of Booking.com, and Caleb was able to find the only place still available on the website ... a vacation rental house near the bridge. And it was only 45 Euro for the night.
The owner showed up fairly quickly to let us in and give us the keys; she was sooooo friendly and accommodating and made us feel really at home. She did speak enough English for us to easily communicate. When she saw we were on pilgrimage, she even offered to bring us some dinner from her family's evening meal. We politely thanked her and told her we already had made dinner plans, but when we later returned from an evening walk around Los Arcos and having dinner, we found a big bowl of fresh fruit on the kitchen counter when we got back.
We each had our own bedroom and bathroom; it had a washer, dryer and full kitchen. The huge backyard had large trees with loads of shade and an above ground pool (which we avoided, not knowing how well maintained and sanitized it might have been.)
It was a nice change of pace and a really refreshing and restful break. The next morning I felt the most rested I had been for several days.
