This was an exceptional Airbnb experience.
First, the pictures were true to form, the apartment is recently renovated, stylish, very comfortable - great REAL beds, separate bedrooms and baths - great for our two couples, and very centrally located. Also a very nice, new, clean, and safe public parking garage 5 minutes away.
This is where the "15-star" rating benefits start: we arrived in Milan early on Sunday because we had F1 tickets for the race in Monza. Communication was highly responsive. We were met in front of the apartment and we were able to store our luggage in a nearby building storage unit (the apartment was occupied by other guests). When cleaning was complete they moved our bags into the apartment and texted us. Very nice gesture.
Upon return that night we found two beers in the fridge - very nice touch.
We were able to name our checkout time (11am).
In sum, this was a very convenient and perfect location for our purposes. Great access for walking central Milan, using public transit, driving, etc. The apartment is super comfortable and well maintained. Communication was great.
