The best bank I've had an account with
I can only speak about the Italian branches, but Fineco has been the most reliable and supportive bank I have had an account with. Not only that, they have very good English!
I set up my account with only the documents stated as necessary with no delays (compared to others in Italy which required outdated documents and special forms for me as a non-EU citizen), in person at a Milan office; my advisor spoke perfect English and enunciated contract terms very well.
Afterwards, I have been using the website and app for banking, whose interface leaves a little to be desired (the website is more disorganised in this aspect), however I have never had issues or bugs. I am not a trader in crypto or stocks etc but the multi-currency exchange features have saved me often from higher commission fees.
Due to the bureaucracy, I have had some issues with some processes, that are also outdated, such as the need for certain verifications and use of postal delivery rather than being completely online or in person, however the customer support is available even when Italian banks would usually be closed, on non-working days as well. Responses are always prompt and helpful and it has simplified my navigation of the Italian administrative processes a lot :D
Overall, I always recommend Fineco to all my friends, especially the international ones, with the caveat that Fineco does not seem to be absolutely fully autonomous, relying on the UniCredit ATM circuit for example, and not being available directly under the PagoPA system - these have never caused any real issues for me in the four years I have been with them.
