Question Hotel in Erfurt: Zumnorde or Kramerbrucke?

I'm planning a trip to Erfurt and can't decide between Hotel Zumnorde and Hotel Kramerbrucke. The rooms directly on the bridge at the latter sound amazing, but I've heard great things about Zumnorde's service. Has anyone stayed at either of these places? How was your experience, especially concerning room comfort, location, and overall value? I'd really appreciate some insights to help me make a choice.
