Good banking with good support
I am a big fan of branchless banking and N26 does it well despite it is relatively new bank. There are still rough corners here and there but I am sure they will make it better over the time.

For example, the app's user experience is not the best. Tapping on "+" to transfer money is very counter intuitive. Or another example, I would prefer SWIFT option instead of Transferwise due to the low costs in my case. But they don't have that option. But these are not major problems.
