Pros: Everything was pretty easy. We paid at the agency when we picked up the car. Employees were nice and helpful.
Really small car but super cute and enough for what we wanted to do.
Cons: Not a big deal but it would have been nice to know that when returning the car there was a specific place to enter the parking lot (rental in Paris, France so quite confusing anyway).
I ended up being pulled over by the police because I had not noticed the continuous line on the road (I was too focused on finding the parking lot). This is my mistake of course but an employee admitted that this happens quite often so I guess a warning or a small map could be useful :)
Cons: When we dropped if off in Paris, the drop off station was very sketchy in a below-ground parking lot and the employees didn't seem to know what to do with us. We also had to ask them to give us a receipt and confirm how much of our hold would be charged. It all felt very unprofessional and confusing.
