We stayed 2 nights at Concetta's, she is very nice and helpful. Everything in the apartment is very well organized and clean. We didn't get to see Milano since we were at a conference but the neighborhood had everything we needed. Concetta recommended restaurant da Gianinno? and we had a nice dinner with life music there. To get from Central station to her place it was uncomplicated and fast. She also has air conditioner in the room if it gets too hot.
I would recommend her place :)
