Roberta's place was clean and nicely decorated. My friends and I had a comfortable stay. She responds very quickly, greeted us when we arrived and provided great tips on where to eat. Location is conveniently by Navigli, with all the bars and restaurants. It is by a train garage and the trains going right by the ground-floor apartment, so it does get a bit loud in the mornings. But not a big deal since you'll be so tired from exploring anyways. Nice stay and would recommend.
