Good apartment in a great location in the middle of everything. Take their warnings seriously if you don’t know Zurich very well. It’s smack in the middle of the loudest, most 24/7 area of Zurich, and it’s loud at night, especially on weekends. You will not want to sleep with open windows. We’re a family with a young kid so luckily we have a sound machine anyway ;) If you don’t know what you’re getting into, I would heed their warning and avoid the listing if you’re a family with young kids – but we had a great time as I grew up here and know the area well.
With that out of the way, it’s a good apartment with a beautiful rooftop terrace, and would be super suitable for a group of young people who want to go out themselves, or even just if you know about it ahead of time. The host communicated amazingly and I got a reply within an hour or two (during Swiss business hours) to any message.
