Aside from the transportation issues (gettiing to either property from the airport is quite easy and inexpensive in my opinon), if you don't mind smoking, then the Zurich PH is a great property. But surprisingly, the PH in Milan restricts smoking much more efficiently and that makes a difference if you spend any time in the public areas (lobby lounge, restaurant) of the hotel. Both are very nice properties. It goes without saying that if you are visiting this time of the year, take an overcoat.
