We have no major complaints but the hotel also won't wow you. The premises are nice. We enjoyed coffee in the courtyard, and found the staff to be friendly.
However, the AC didn't work. We had a bit of an ant problem in our room. And the hotel isn't near any important sites in Milan nor good shopping or dining.
We only stayed one night, and we slept fine, but if we stay in Milan again, we may look tor a more impressive hotel.
