I worked there for a few months in the early 80's and really enjoyed the city, albeit it was very expensive to eat & drink in. There are a lot of museums there, covering a wide range of subjects and one that perhaps surprisingly is a great visit is the International Red Cross Museum; esp. for anyone interested in military conflicts over the years. The airport was great for shopping, head and shoulders above most others, but it's nearly 9 years since I last transited it so not sure if it compares as well now.
And of course there are lots of watch shops.......... :lol:
