Clean, convenient and safe! Swissotel Oerlikon is 10 min away by train from the Hauptbahnhof or 15-20min by tram to the city center and best of all 5 min from the airport by train. There is a Migros supermarket right across the street with a restaurant so breakfast, lunch or dinner is not a problem. The room is clean and sleep quality is great. They also allow you to use the pool and spa on the 32nd floor as part of your stay. I will definitely come back here whenever I am in Zuerich! Oerlikon is a great spot to feel right in the center of life in Zurich outside the tourist-filled Altstadt!
