Have parked there several times this summer.
It is quite a good alternative to expensive parking at the airport.
Park 'n Fly offer discount coupons on their web, and their competitor Vinci next to Hilton accept them.
Park 'n Fly lots are fenced and it is all automated. Lot Express A seems to be the cheapest for the moment.
Allow extra time to be picked up and taken to the airport by a courtesy shuttle bus.
Overall, to be recommended, just as Vinci that is a little bit closer and is staffed 24 hours a day. You ned a shuttle bus as well, though.
