If at all possible - avoid using Banco de Valencia.
I have my mortgage with them and they are awful to deal with. Terrible 'customer service' - if you can call it that !
Easily the worst company I've ever come across.
p.s. - They'll try and sting you on the insurances every year. Just remember that the only insurance you're obliged to buy is buildings insurance which has to cover the outstanding total of the mortgage as a minimum.
