Very nice clean and practical apartment.
We came as 3, me and 2 children.
The apartment can be seen as a very big hotel room on 2 floors, so ideal for 2, nevertheless it was more than ok for us, as it would be for 4 I guess.
The set up and supplies available makes it very professional, making then our stay easy and practical. The apartement has its separate entrance, and no outside. Roberta is easy to reach and helpful.
Tramway is passing in front of the apartement, more less 5 stops to the duomo. The walk to the duomo is around 20-30 min (with 2 kids), with nice churches or sites to visit on the way or shops. The area of the apartment itself is also interesting for restaurants.
There is a supermarket open until 11pm every day next to the place.
Perfect place to visit Milano, I recommand it.
