Beautiful Sleepy town. The falls are pretty. I suggest you rent a car if you are visiting though, we only saw 2-3 taxis the whole time we were there.
The town centre is not close to the Bahnhof. But you also have to wait long time for the buses that go between.
So if you do not have heavy luggage, I suggest you simply walk to the town centre which is only around 15 minutes but with steep slopes to climb.
