The Airbnb is extremely well located, it is a couple of steps away from Zurich HB. No noise from the trains despite the proximity. Currently, there is some major construction going on outside, and it starts around 8:00 am, which not a big problem since we were out all day.
It's also conveniently located by the Sihl river and the Swiss National Museum. There is a tramway stop right in front of the Airbnb which makes it easy to go around Zurich. Additionally, there is a Covid test center located about a 3-min walk from the Airbnb.
The apartment was spacious and exactly as pictured. Check-in instructions were very clear, accurate, and contactless. The checkout follows the same process.
