Tobias' place is in a great location, close to lots of restaurants, the river, the tram, and a short walk to the main Zurich HB train station. The apartment is small but liveable and great as a home base for exploring. The apartment is not any noisier than a standard city apartment, but if you're not used to city noise, bring earplugs. It didn't bother us at all, coming from NYC. Tobias is good at communicating but we would recommend confirming check in plans more than once to make sure he and his hosting partner are on the same page. I would stay here again, it's great value for Zurich.
