Best online bank without a doubt
It is actually the best banking experience ever. I have been using N26 for more than two years now and I can say that it has been the best. Security, application, support, transactions... everything is super smooth and easy.
Despite it doesn't have a physical place where you can go, it is as easy as clicking on support to start getting attention from a bot or an agent. 
If you are doubting of opening an account or not and you are reading this, just do it. In the first few days you will find yourself happy with the decision you made.
