We loved this airbnb. It is literally steps away from the train station (2 underground entrances right beside the apartment building), but there is no noise from the trains despite the proximity. There is however some major construction going on outside right now (April 2022) so it was pretty noisy from that. It's also located by the Sihl river and Swiss National Museum, and only 10-15 minutes walk from Old Town. The best part about the location is that it shares the building with the Migros grocery store, which was extremely convenient. There are many nearby restaurants both in the Zurich HB station and in the town.
The apartment was spacious and exactly as pictured. Check in instructions were super clear, accurate, and contactless. Same with checkout (no instructions but Jeyla replied immediately). The bed was comfortable. Pillows full but a bit small, would have liked a few extra. The windows are floor to ceiling and open to a cute town square where you can see some restaurants. The flat screen TV is a smart TV so you can watch YouTube and use Jeyla's Netflix account, complimentary. WiFi is very fast and strong, we were able to do video calls with no problem. Laundry is also FREE - both a washer and dryer are in the apartment building, but you must provide your own laundry powder/detergent. The only few bad things about the apartment: the shower's water pressure is weak, the metal part of the faucet in the shower gets VERY hot (not a problem, just don't touch it by accident like I did), only one trash bag was provided (and we were unclear what to do with recycle items), and some of the kitchen items were hard to reach because the cabinet is very tall rather than wide. None were deal breakers for us.
