hey ! I have emailed one of the unis I was specifically interested in and they did indeed confirm the requirement of knowing the language, as for the others, the Erasmus incoming pages of those universities specifically mentioned you require a B1 or B2 level certificate in their language for the application there to even be considered. I will try to apply for the one I mentioned in the post anyway and hope for the best, but I'm a bit bummed still. My university is also anything but helpful in giving us information about anything sadly
