The apartment is well situated, clean and well maintained. It is bigger than it looks on the pictures. Bakeries, supermarkets and the Navigli area are close by. From the windows of the room, you can see the top of Duomo and (in good weather) even the Alps!
Andrea made me feel very welcome and was always helpful, both with practical things and more general questions about Italian society. It was a very pleasant stay and it is not surprising that many people want to stay at Andrea's apartment.
