We've been extremely well received by Anna and her family!
The flat is very clean, full of light and well equipped. She offered fruits and everything to have breakfast, a true B&B! She also provided us with fresh towels. It's very well connected and close to the centre.
The only thing is that it can be too noisy for some people because of the tram down the street, but this situation is pretty frequent in Milan. So you may consider to use earplugs.
Despite this, I would definitely recommend to book a room with Anna, even for a week!
