Renting a car
In Copenhagen, you can use GoMore that is a service you can use to rent a car to people living in Copenhagen.
It’s usually cheaper than renting a car to big rental corporate like Europcar, Sixt, etc…
Moreover, everything is controled via the app.
You book the car, unlock it thanks to phone bluetooth and drive wherever you want.
You must be careful when parking the car, everything in Denmark is very strict and there is a lot of controls. Make sure the parking spot let your park without additional fees. Otherwise you can get fined pretty easily, and the fines are quite expensive.
GreenMobility
GreenMobility is quite popular, but it’s not meant for long trips. It’s better suited for when you need a car within Copenhagen.
They offer electric cars that you can easily rent to get around the city.
