Nice tiny apartment but it is not what you expect from the photos, which give an idea of a bigger space and the furniture is not really what you expect from the pictures shown (the bed is not comfortable at all). Although it is tiny, it is well thought and distributed, but the idea they give you of a terrace with duomo view it is not quite true, it is a shared terrace and considering this and what it is previously mentioned, it felt kind of false advertisement to me...
It does have a good location, but from previous experiences in other Airbnb flats, there are better options regarding this aspect.
The communication is not very personal, which gave me the impression that everything was an automated response, but that it is only available to certain hours a day (I sent a message at 10 o'clock at night and I did not have a reply until 9:30 the next day).
When they mention the check out time is at 10 AM they will make no exception (not even an hour) so do take this into consideration.
Overall I would say that from all the Airbnb flats I have stayed in Milan (I visit twice a year), this would be the one I wouldn’t repeat.
