I highly recommend Giuliana's apt ! Contact with Giuliana and her sister was very easy. The apt is spacious, comfortable and very clean. The place is very convenient, Metro and Tramway are just down the street, as well as nice restaurants and bars. Grocery store at 5min walk and opened on Sunday ;-). It's very easy to visit the city from this area.
Giuliana was very helpful and gave us great advices. I surely come back for my next trip to Milano !
