Cheap and clean
Geneva hotels are fairly expensive and this complex stands out in that manner. Very cheap and located right at the French border. Simply take the tram and pass the border to get there (1 minute walk).
The studio was large (you can easily occupy this with a group of 5 - 10 people, if you take sleeping bags). It was clean and even had a full kitchen (including microwave).
The only downside was the bed, but then again, for that price, you can't complain too much.
Very much recommended!
