I stayed at Katie's place during my 24 hour layover in Zurich. It was in the perfect location - walking distance to Grossmuenster and other areas as well. I was solo traveling so had no other guests with me. I took some pastries from a nearby cafe and sat near the water (walking distance from Katie's place) for a couple of hours. The airbnb itself was very clean as was the bathroom (which provided all amenities). I didn't mind that it was in the office since I had my own key and no one else was using the bathroom or the office. Since I only had 24 hours I spent as much time as I could exploring. It helped that it was summer and didn't get dark until 9 pm. I never ended up hearing the music actually! I returned home close after midnight and they had already packed up! I didn't meet Katie but I met her associate who was very friendly and helped me with the check-in process. Turns out Mumford and Sons have actually made a spontaneous appearance at this bar! If you are in Zurich and looking for a great location this is definitely it.
