You no doubt stayed in Kloten, which isn’t actually a suburb of Zuerich, but a small town only a few kilometers north. It’s the town where the airport is located. That’s actually where I lived, in Kloten. Since I no longer have a home there, I stay at the Hotel Welcome Inn, which is very close to the airport and has a shuttle to and from the airport. There’s also a Hotel Allegra, but I love the Welcome Inn.
Zuerich Old Town is very beautiful. It would have been nice if you’d had more time. Zuerich is very accessible by train, and shopping in the main train station alone is fun. There are many, many ethnic restaurants in Zuerich, all of them with great food. Zuerich is a lot nicer in the summer, though, and summers are warm but not oppressively hot. Lots of flowers in the summer, and the lake is gorgeous and so clean.
Tbe Swiss are very efficient and expect you to be very efficient, too, but once you get used to them, they are quite nice. (Took me some time to get used to living in Switzerland. Zuerich is very focused on business and finance; the Italian canton of Ticino, which has palm trees, is much better for enjoyment. There, I stay at the Hotel Parc Rovio and make it a point to go to Bellagio, Italy.)
