I had a great time at Barbara's place. The house is old but in good shape. The bed was comfortabel, the bedroom was spacious and the kitchen quite good. If you are sensitive to noise and light during sleep (like me) then make sure to bring ear plugs and an eye mask because it can be quite noisy and light in the morning or during the day.
The location is good and well connected. It is a bit far from a metro stop. But right in front you have bus and trams that can take you to the metro or the city center. The latter is quite slow if you take a tram, though.
Barbara was extremely helpful during the whole stay. She was always willing to help and provide tips. We had great conversations and also went for dinner together. Because I'm celiac she even separated pans, plates, cooking utensils and other things just for me.
If you need a place to stay in Milan I totally recommend this one!
