This hotel (and milan itself actually) was a concession to my wife on our honeymoon through Italy. I get to site see in Rome if we go shopping in Milan. Naive on my part but never mind. Milan was beautiful, and the night life, shops and restaurants were absolutely amazing. Everything was so easy to find (and they even give you a map of the city with all the major shops on it (ask at reception.)
As to the hotel then. Fantastic, no over words for it. The service was quick and helpful (everyone spoke very good english which always helps) and really tried to please everyone no matter how busy it was. The rooms are beautiful, amazing bathrooms, service, beds (you can even request what tog you want for your mattress, beds sheets etc. incredible. And as to the restaurant, the food was superb, breakfast, lunch, dinner. You almost din't want to eat outside. Would recommend booking before hand though.
The hotel also had all the spa and pampering requirements my wife could ask for to spoil herself. More of a couples hotel, though i suppose that milan itself is more of a couples (or women's) vacation city anyway.
Be prepared to pay, though defiantly worth every penny.
