We are flying to to Ciudad Real (100 miles south of Madrid) in October, and planning to drive down to the coast with a day's stop at Cordoba.
I was hoping to find a cheap, clean, travelodge type stopover for the four of us (2 adults and 2 teenagers) near Cordoba - along or near the E-4. However, there doesn't seem to be anything that won't set us back by at least 120 Euros. We appear to need 2 rooms - I haven't found any suitable rooms for 4. We would be arriving at the hotel close to midnight.
Are there any cheap hotel/motel chains in that area of Spain? Something like a Travelodge, HIExpress, Ibis, Etap, B&B (as in the French motels). All of these I've searched for, with no luck.

Thanks in advance.
