Hello all, I will be in Geneva in September for about three nights (got myself a tour set up for the CERN super collider...woohoo!) and am looking to stay in a hotel as close to the city center as possible.

Any recommendations on good hotels in the $150-$250 range in the Accor hotel family? I'm not wedded to a particular brand as part of the family. It will be my first time there and I've heard beautiful things about Geneva.
