We're taking a hiking vacation at Zermatt this summer, but we wanted to spend a week of unorganized time in Switzerland beforehand. We're flying into Zurich. I was thinking of getting an airbnb room in Zurich for a week, and making day trips from Zurich. I don't have any idea how long it takes to get to Bern and Basel and Luzern, but those are places that might interest us.
Any suggestions on how to spend a nice 5 or 6 days in Switzerland? I guess I have a preference for areas where I can speak German.
