Prior to our visit the staff were so incredibly helpful. We had to have various things shipped to the hotel and nothing was too much trouble. They were the same throughout our stay - willing to help with everything.
The location of the hotel is perfect - a short walk through a beautiful park to town or if you're feeling lazy, the 11 and 14 trams stop right at the front door.
We stayed in apartment number 104 which was on the tenth floor. We had a huge roof terrace with amazing views over the city.
The apartment itself was spotless and really nicely decorated. All of the amenities were great including coffee machine, the well equipped kitchen and the washing machine and dryer.
I would highly recommend staying at EMA House when visiting Zurich.
