Overall, it's quite good. The car pickup point is at a corner of Milan Central Station. Look for the Blue Elephant car rental; the three companies are together there. Remember to attach a photo to the QEEQ white form, otherwise, the staff will ask you to take one, and the photo booth is at the metro transfer area of the train station. They will ask if you need insurance, but if you say you have already bought it, they won't ask again.
