Positives: Excellent location! Only a few minutes walk to Porta Genova station, the canals of Navigli, and a grocery store. Communication and check-in were clear and easy. Check-out as well as there is a box to leave the keys. The apartment interior was as described. We were able to cook a full meal one evening.
Negative: The listing says that it is very quiet with the front opening into the courtyard. However, the bedroom window shares an alley with a small music venue (jazz club?) and it was loud both nights of our stay (a Friday and Saturday). Perhaps it is more quiet other nights? But it was difficult to fall asleep before 1am. The area is known for it's nightlife so not a surprise but fair warning.
