Andreas was excellent at communicating. I asked him about the Rhine Falls a few weeks prior to my stay and he even took a picture of it for me a few days later when he happened to pass it by. The inside was as described and it was not too far of a walk from the main areas of Zurich. We did hear the bell at night and in the morning but I did not think it was overly intrusive. If you go to bed early you can always bring ear plugs to block the sound of the bell out.
