Johannes was incredibly helpful, our train was cancelled from Paris to Zurich due to the strikes and I did not know about this from the train company. No email was sent to me, but Johannes without me asking him notified me of the cancellation and allowed me to get out ahead and buy plane tickets. The apartment makes travel crazy easy, the tram system is beautifully designed. I loved the suggestions to Uetliberg and all the additional information. I will stay again if I go to Zurich.
