I am not used to booking airbnbs in that price range (a bit expensive for me) but for our 4-day stay in Milan it was absolutely perfect.
It's exceptionally well located, basically same distance from the Castle, the Duomo, Da Vinci's Last Supper, etc. The only area that's a bit far is Navigli and it's still only 25 mns.
Bedding is good, living area is very comfortable, the kitchen is well equipped. Only thing to know is that you don't have a view to enjoy (it's not that there are buildings in your face, but they are there). But there's a lot of light thanks to the very high windows.
Definitely recommend, it felt like a home away from home and Simone was very accomodating with our check-in and check-out hours.
