The staff handling the procedures were very nice, especially a friendly young lady. However, the person who gave us the keys just left after handing them over. The car had a security system that we were unaware of. After parking for 2 hours and going for a walk, we couldn't start the car. We called the store, but nobody answered. Finally, we had to call roadside assistance. It turned out we just needed to press a button inside the car that looked like a dashcam. No one told us about this, which caused a significant delay in our trip. We had to use the car key to unlock the car every time we opened it, which was very inconvenient. Also, don't drive a big car in Milan! They switched us to an SUV, which became a burden instead.
