There were two main problems we experienced with this place:
1) WiFi - we specifically sought a place with WiFi, as my wife did not have a European SIM. Having noted an earlier Airbnb review complaining that the WiFi did not work, I checked with the host about two days prior that the WiFi was working and she assured us it was. Upon arrival, it did not work. I took the router to the provider who informed us it was definitely not working. The host was unable to resolve this but refunded us €20.
2) Room temperature - we were in Milan in mid-September. The room got very hot, to the extent I had to have a wet sheet over me to be able to sleep. There is no fan supplied, and it is not possible to sleep with the window open as it is too loud.
Other than these two issues the room was neat, clean and well stocked. If you intend on cooking, please note there are only butter knives supplied, no sharp kitchen knives.
If you are catching the Train to Milan Central, this apartment is in an ideal location, only 5 minutes walk. There are also a lot of late night eateries, in particular Miscusi across the square, the best pasta we had in Italy.
