There is a common issue with car rental companies abroad nowadays. If you purchase insurance through the platform, they won't force you to buy additional insurance, but they charge a very high deposit. This is not just with this company; I have noticed the same issue with several others. This company, however, has an additional issue: they charge a €36 cleaning fee if the car interior is a bit dirty upon return. This is the first time I've encountered this, and it doesn't feel great. Everything else is fine, though.
