We had a wonderful stay in the EMA House apartment. With 3 bedrooms, and 2.5 baths, it was plenty of room for 4 of us. The apartment is well located, walkable to most everything.
We did use their parking for our rental car, which was only 1 short block from the apartment. The check in process was easy, and the staff members were excellent.
I highly recommend the EMA House and would definitely stay again during my next visit to Zurich.
