Stayed at the Radisson Blu the night before departing Switzerland.
I think the reviews are overstating this hotel somewhat significantly.
It's perfectly fine. But when you're a hotel that's basically ON the airport, then there are two things that you need to do well: allow for a great nights sleep (prior to flights) and have conference space.
Unfortunately the latter got in the way of the former. I didn't think to ask for a room that wasn't below the conference space and was greeted with a room that communicated the sound of everyone moving around upstairs like they were in the room. Constant movement interrupted any hope of a good night's sleep. The uncomfortable bed made that worse.
The hotel is also DARK. The room we had overlooked the interior courtyard, and for some ridiculous reason included NO overhead lighting in the room at all. Trying to get some paperwork done was a significant challenge as none of the lights in the room lit up the room enough. It's baffling. They put a light over the toilet, but there's no light over the bed - just a couple of dim lights on the side table. It wasn't just the room. The hallways were dark, the lobby is dark, everything is dark.
Ultimately, this is a hotel for people that are attending a conference. They're not paying for it with their own money, so the amenities are fine for them. If you're using your own money though? Choose elsewhere.
(Breakfast was not included in my room - it was an expensive option I declined)
