I highly recommend Giuliana's apartment. The private room is quiet, stylish and very comfortable. The bathroom is modern and clean. The apartment is located outside the city centre, but it is well-connected by buses and metro. You can easily reach Duomo in half an hour taking bus 86 plus the M1 from Precotto tube station. In Precotto area you will find local cafès, supermarkets and a few restaurants. At 5 min. walking distance from the apartment there is a shopping mall.
Ilaria, Giuliana's sister, was very helpful during my stay.
