I really like Marco's place. It was very great for me and my friend to live there. The place is a bit far from the center but still it's very good and affordable. Actually we booked a hostel in the center beforehand, but we had very awful experience with the same kind of cheap and dirty hostels in Rome, we decided to cancel and came up with Marco's place. Same amount of budget but completely different living condition.
Marco is also a very friendly and considerate host. The breakfasts we received from him were so big. And he never hesitated to suggest us what to do to have a nice experience in Milan.
