The apartment was great, right in the center of the city, not very spacious but with a huge terrace.
Massimo and Andrea seem nice, but communication with them was fairly spotty. There was nobody outside the apartment upon our arrival despite our early arrangements with Massimo about the time and place of our meeting.
On the Airbnb's Milano Short Term Rent offers transportation from Linate airport at 25 Europs. In his communication with us Massimo offered a "special rate" of 35 Euros. We took a taxi and paid 25 Euros including the tip.
All in all, if you don't mind the attitude, you will like the apartment and enjoy your stay in Milan.
