Mario's place deserves a 10/10. The location is perfect. Very close to the Zurich main station as well as directly next to a stop on a direct tram line to/from the airport. We were able to walk from the apartment to everywhere that we wanted to go. The amenities were above and beyond. The apartment was very clean. Mario let us store our bags both before checkin and after checkout. Mario's hospitality was fantastic. We will absolutely stay at Mario's place again next time we are in Zurich.
