Hi there,
Be aware that
Switzerland is a very expensive country and cheap hotel accommodations are hard to come by, unless you go the Hostel route. Having said this, I found some of the cheapest hotels in the town of Cointrin in Geneva.
These recommendations start from $90 so, it is best to check before you travel:
* The Trente Trois
* The Ramada Park Hotel Genève
Hope this helps
