The check in was easy because a women opened up the doors so we had luck. The view from the apartments balcony was so nice. Although the apartment is small, it had everything you need and it was sparking clean. However I would not recommend it for a longer stay, as the kitchen is so small and you can not cook much in it. The apartment is perfect for two people and for a weekend getaway. It is close to Milano Centrale Station and not so far from the Duomo Cathedral (about four-five stations with metro). The neighborhood is a little bit creepy and not so clean (you do not have a picture you are in Milan).
About the communication with Massimo, he was not responding to my AirBnb messages so I had to contact him on WhatsApp and he always replied in a really short manner of time. I like to get to know the hosts when coming, but unfortunately we have not met Massimo because it is a self check in apartment.
The total value of the apartment for the price you pay is okay, fairly priced apartment, looking like the pictures.
