If you like to be pampered visit the B'eau Rivage Palace Hotel in Ouchy, enjoy a coffee and a piece of 'Tarte du Pommes' on the beautiful terrace overlooking Lake Geneva - it's stunning! Also have a look around the hotel inside, you'll find some amazing architecture.
Good city to walk around, especially in the old quarter nearby Cathedral. Cathedral itself holds lots of impressive stained glasses which are really remarkable.
Ouchy area is also attractive, take a boat to Evian for a daytrip sounds interesting, and which I did :- Pity that Olympic Museum has been closed years' time, I wish to visit someday once restoration is over.
