loud noises, not speed dependent, and not speed dependent

Hello, I’m a bit desperate. I’m on vacation, car (Twingo, Phase2) is standing at the airport. I just got there. On the way the car started to hear extremely loud noises in the interior (outside there was almost nothing to hear). Noises come only while driving, but are neither speed-dependent, nor speed-dependent, and stop only when you stand still. Actually everything is done on the car…wheel bearings don’t have 10,000km yet, no wheel gets warm. It is so loud that a conversation in the vehicle is hardly possible. Sounds like an unlubricated axle. Should I still drive home with the car? Does anyone have an idea what that could be? Come home on Sunday night, so there’s nothing to do with the workshop.
