You can temporarily park in underground parking lots. When using the Beast Rent app, please be mindful that the connection between the car and the app can be weaker and therefore slow down the process a little bit.
P.S. Please do not park Beast vehicles in deeper underground parking lots than the 1st floor. In deep underground parking lots the connection to the vehicle can be lost and the application cannot be used anymore. In this case, our technical team will have to provide assistance and a surcharge of 50 EUR will be added to the rental fee.
