I lived in Roberta’s apartment for almost 7 months and can’t say enough good things - I would give it 10 stars if I could. It is very well furnished and has all the kitchen utensils/pots and pans/towels/blankets/etc that I needed, so it would be very convenient for any length stay. It is clear that lots of care went into the decor; I loved being surrounded by books and art. I felt very much at home there.
Roberta herself was always very responsive and understanding. This was my first time living alone, so I had a lot of questions (some of them were silly, like how tilt windows work) but Roberta always answered very quickly and kindly.
The location is a bit outside the city center, but it is nicely located on the 24 tram line, which connects you to the metro and the duomo area. I personally enjoyed being a little bit farther from the center; the area seemed safe and there were several large supermarkets in easy walking distance. It is also easy walking distance to Fondazione Prada and ICA Milano (contemporary art).
Overall, I would highly recommend Roberta’s place (and would love to return myself someday)!!
