We rented this flat for one month as we were in MIlan for business reasons. Everything is perfect. Location, porter, public transportation, a fast wifi connection, shops and supermarkets.
Andrea and Federica are such nice people and amazing hosts they even provided us with some groceries on the day of arrival.
I warmly suggest to rent it. You're next to the city centre but at the same time you're not forced to pay the "C area" tax to drive downtown. If we have to come back to Milan we surely book it again.
