While we only stayed in Susanna's apartment for the night as we had to fly out early the next morning the experience was great! Susanna met us at the apartment even though we arrived close to 1030pm (2230). She was very friendly and gave us a great walk through of the building and apartment. It was very spacious, had plenty of rooms and bathrooms to fit all 7 of us, and it was a quick and easy walk from the train station.
I would definitely recommend it for large families or groups looking for a nice apartment close to the center of Milan.
