Mario’s place was just what we needed for a few days in Zurich. The location is really ideal, ~30 min by train from the Zurich airport, and ~5 min walk to the Zurich main train station that will take you almost anywhere in Switzerland. On top of that the check in/check out process was smooth, the apartment was really nice/safe, and it was very close to some great cafes and restaurants in the heart of Zurich.
If you are traveling alone or with your partner I couldn’t suggest Mario’s place more.
