You can enter and exit this car park automatically.
You can modify/cancel the dates of your reservation up to 1 hour before the arrival time.
During your stay you will only be able to enter and leave the car park once.
During your stay you can make use of the entire network of car parks of this operator available at Parclick.
During your stay you can enter and leave the parking lot as many times as you want.
Compared to other, fair prices for a very central location. You have to use an app, there is no other way of entering and exiting, even as a pedestrian: you open the app, choose exit as a pedestrian and the big door opens. Everything worked just fine.
Parking here was the best decision I made during my time in Rotterdam. I avoided the bad weather, especially the snow.
