I stayed at Fabrizio's place for two months. The place was nice, well-located (within walking distance of the train station and the university where I worked, and just next to a subway station to go to the city center), and well-furbished (be aware though that you need an adapter for all electric plugs, except one in the kitchen). The AC worked well, useful in the summer. There are two other rooms in the flat, all rented on airbnb, so there will be other people coming back and forth (warm hello to those I had the pleasure to meet!). I had some problems with the shutters, wich cannot be completely closed; as a consequence, there was still some light and noise from the street coming at night. Fabrizio, however, gave me a night mask, which helped. All in all, this is a good and affordable place to stay in Milan; I would recommand it if you need to go there for several weeks.
