We had a wonderful stay in Milan. We did not stay in the apartment near the Duomo because the apartment was flooded the day before we arrived. The host offered us an apartment in Brera and a partial refund. We were very happy with the services. However, we have not received a message about the partial refund up until two weeks after our stay, which is disappointing. I trust the host that we will get in contact about this matter.
Other than that, we had a wonderfully stay in Milan and are happy with the services provided by the host. I would highly recommend Brera to stay when in Milan, because everything is within walking distance and it is a peaceful and fun district.
