If you are thinking about opening a French bank account, you could do a lot worse than Mona bank. Me and Mr H have had both our personal and business accounts with them for Well over five years now and as banks go, they are very good. The app / interface is also extremely user friendly which counts for a lot in my book.
They are currently doing their ‘sign up a friend and you both get get free money’ promotions… This is one of the more generous schemes on the market so it won’t be around long.
They are offering up to 120€ If you open an account with them - if you are interested, DM me your name / email and I will sign you up!
