Santander- Storing a bike box for a week

[molly]

Can anyone suggest a solution for storing my bike box whilst I tour the Picos for a week. Maybe a cycle friendly hotel, b&b or hostel within reasonable distance from Santander airport for first and last night stay? Or if I went with a disposable box then a bike shop that would supply me with a new cardboard box for the return journey.

I'd be looking for a dependable hotel chain (Ibis budget, etc) with a bike store cage. If you book a room for either end of your trip you are unlikely to be refused if you ask if you can leave something there. Make a small hole in the box to allow you to lock it to something.
