I stayed at Gio's apartment for about 5 days during Milan Fashion Week and it was a great experience. It's about as close to the center as you can get without being in the dead center itself. The apartment is near to amazing restaurant and good shopping options as well as the public gardens in Milan. As a host, Gio is wonderful. She greets you at the apartment and checks in on you throughout your stay. Her apartment is a great size and extremely accommodating. If you're looking for a sterile no one else has been here accommodations, this might not be the place for you as this feels extremely like staying at a friend's apartment. Even as there was an incident post stay, Gio handled it professionally until it was resolved and was great to liaise with. I had a terrible time dealing with Air BnB's internal team right before my trip and Gio made me want to use the service again. On the whole I felt very safe in the neighborhood as a woman traveling alone.
