Hotel in Zurich

It would help if you did a little research on your own first to see what the market is like and then post with your budget, potential hotels you are considering, what you plan to do while you're there etc. It is hard to recommend anything without knowing what you are looking for - people have vastly different preferences and ideas about what a good hotel is...

I was very pleased with this hotel in Zürich - https://fredhotels.ch/en/fred-hotel-zurich-hauptbahnhof/ . It's within walking distance to the main rail station, and right across the street from the location where many city tour buses depart from.

You could also check the Rick Steves Switzerland guidebook, as I believe there are some hotel listings there.

I'm pretty sure a guy named Rick Steves has done much of this work for you
