My boyfriend and I stayed in Chris' apartment for 5 nights, and it was amazing! We didn't stay in this exact apartment though, because the slightly bigger apartment on the same floor was also available ('A1 Lage in Zürich nur 10 Fussminuten vom Bahnhof !') and Chris kindly offered us to get this free upgrade. This is why I can't go into detail about this ('Best adress') apartment itself, but I can tell you that everything was even better than expected! The check-in was easy, Chris was quick to respond to our questions, the kitchen was equiped with everything we needed, we could use the washing machine in the basement, the view (we were on the same 3rd floor as this 'Best adress' apartment) was amazing and the location is super super central! I would definitely recommend staying here or in the apartment we ended up staying. If we ever come back to Zürich we will definitely stay at Chris :) Thanks for everything!
