We set it up with Nationwide here before we went over, filling in all the necessary paperwork. They gave us details to take to Finansbank & then all it took was for Ayse to fax them whatever they had asked for from Nationwide, a very quick telephone call from us to our Nationwide branch (they gave us the direct number- make sure you have that!) & it was received & in our Finansbank account the next day.
lloyds & Barclays said it couldn't be done, maybe 1 of them said 3 weeks, was so long ago now? But no probs with Nationwide.
