Long-term parking is outdoors, in neat rows in a field. The staff is very friendly. You leave your car at the hotel entrance and it will be parked by valets. The airport shuttle takes you directly to the car where it was parked. The very kind driver transferred our bags from the shuttle to our car without them touching the ground.
Simply the best place to catch your flight at Malpensa.
The shuttle service is excellent. And if you arrive late, there's a restaurant that can fix that.
