I really had a nice stay at this place which is managed by Lucia if I understand well (and not Sandy). The wifi is not that fast, quite average number of 25-30MB/s.
First, the location is really ideal for a stay in Milano to visit the center of the city. Next, Lucia is quite available and flexible on arrival time which makes things very easy.
Furthermore, another room is also rented with Airbnb in the apartment. You can literally here every sentence spoken there and everything that happens in that room or in the bathroom. If you are looking for calm sleep I would suggest you to find another place.
Overall I recommend it, the price suits the expectations!
