Very nice and cosy little town

Yes, all of the amenities of Geneva and the surroundings with few of the exorbitant prices.

BTW, it's St. Julien not Ste. Juliette

St. Julien is great - has everything you need and is well connected to Geneva by direct bus routes. If you have transport check out Vitam Park sport/aqua/commercial centre just up the road.

It's a nice little town, all the amenities you need and not too far from Geneva.  I second the above recommendation for Vitam Park.  One thing to keep in mind if you are planning to work on the Swiss side is that traffic during peak hours (French -> Swiss side in the morning, opposite in the afternoon) can be quite a challenge.  Best of luck!
