Hi everybody!

Does anybody have any experience with the various companies offering valet parking services at Geneva airport (e.g. GVA Park)? 

I have an early flight on sunday and since I live in Annemasse driving seems to be my only option. When Google-ing parking options I came across many sites offering the service of leaving your car with the company at a convenient spot and them parking it at their parking lot for you. If the prices they state online are correct, the valet parking service for my 5 day trip would cost pretty much the same as parking in the cheapest parking lot. It would also save me the hassle of finding a parking spot and walking to the airport. It almost seems too good to be true....? Since I had trouble finding reviews online, I'm asking you friendly people - does anybody here have any experience with these services? Or any other tips for cheap parking near the airport?
