We stayed three nights at Anna's place and it worked out very well. Her flat is located on the sixth floor of a residence, which itself is a 2mn walk from the Precotto metro station (making it very easy to get into the town centre of Milano - 15mn metro ride).
Anna lives there with two other guys, of which one was there to welcome us when Anna couldn't. We got to use the kitchen as much as we wanted to, which was great. The bathroom was shared as well. The double bedroom was nice and spacious with a double bed, a desk and some cupboard space. The WiFi worked very well.
Anna was a very nice host who gave us our private space, even if she lived in the room opposite us. She was very flexible with our departure time.
We had a lovely stay here and would recommend it for anyone wanting to visit Milano and Lake Como!
