Banks in Spain

We have Cajamar's Wefferent online account. You need to open in branch, and keep a small minimum balance, then the rest of your banking is electronic and charge-free. You will pay for any face-to-face in branch services. 

We also use Transferwise for currency exchange. 

Decide what your requirements are and do your due diligence. Some banks have a heavy charging system. 

Hi Laurian thanks for your advice, that's very helpful.
