Lovely 6 days. Beautiful beaches and walks. City of Santander very interesting and very Spanish, not much spoken English which was a bit of a problem. Tourist office only dealt with Santander and not surrounding coast or area which was a bit of a problem, until we worked out where we thought we wanted to go to and found the appropropriate bus timetable at the bus station. We had no car. We found visiting Bilbao for the Guggenheim ok, but you needed to book the bus a day or so ahead, as all the early buses (9.00 am.) were full and the next one with some spaces, not many, was at 11.00 a.m. a bit later than we wanted to go, but it worked out ok and was a great museum to visit.
