I had a definitely nice time at Graziano&Francesca' place.
The location is perfect for who wants to explore the city and for those who go to Bocconi university.
It is close to Milan centre (Dunmo) and Navigili Area. You can find good food around the house and then take a walk by the river. Everything is walking accessible.
House are clean and tidy. Graziano and Ileana are extremely accommodating and helpful. I am new to Milan as an exchange student, Graziano helped me out with room hunting and introduced me tones of good place to go in Milan.
I haven't met Francesca since she is working in other city right now, but she was always checking my situation and send me warm greetings.
They are very good people. I am so happy I booked their house
