Geneva
You should visit Geneva, which is the smallest cosmopolitan city and seat of many international organizations, especially the UNO. The contemplative city on Lake Geneva hosts many world politics conferences.
On the shores of Lake Geneva and the Rhone, promenades invite you to relax, and there are shops in the beautiful shopping streets. If you want to buy a watch in Switzerland, Geneva should be the best place.
Geneva is surrounded by mountains and tranquil villages. A visit to Geneva is worthwhile.
