We stayed one night at Niels and I have to say it was a great experience. Niels was very responsive and we were able to check in early which was extremely helpful for us—we were able to drop off all of our bags and experience Old Town without having to carry everything! The apartment was clean and it has a very nice little balcony which was peaceful to sit on. The beds were very comfortable, also. For his check-in info, Niels gave helpful advice for how to get to his place by using the local tram, which we took and got there without a problem. In general, Zurich’s public transportation is super easy to navigate once you’re using it. The apartment is close to a tram stop and you can get to Old Town within a few minutes, which is great. Overall a great time even though it was a short stay.
