My expectations were low for an airport HIE, but here are some things to know. It was recently remodeled, and I was greeted by a letter from the manager. The outlets in the room were universal, so
no digging out my adapters to charge my devices. The shower was good, and the towels were softer than I expected. The free wifi was reliable enough, and included 3 or 4 devices (you can get more upon request).
There is no restaurant serving dinner, but they had a food truck outside (until pretty late too, well after 9:30 pm) and you can walk to several restaurants.
If you are coming from the GVA car rental, go up a level and out the back of the garage and it's a 5-6 minute walk. I walked from the airport hotel shuttle area (after waiting over 30 minutes for it...), and that walk was under 15 minutes.
One last nice touch was they provided a transit pass for the local bus and maybe rail service. I didn't use it since I was there for only a few hours total, but if I had more time I would have used it to explore Geneva. [Less]
