I stayed for a month with my wife. The apartment has good wifi for smartworking, and has a good space for 2 people. is close by from ametro stations and at waking distance from duomo (30 min). There are some good bars/restaurant close by, and is 20 min walking from navigli.
The building is a bit old and not super well preserved, and the surrounding area is not the prettiest in Milano. In the apartment i had some issues with the hot water in the shower because it last only a few minutes, and outside is a bit noisy at times, even if there are double glass windows, so some times it was hard to sleep well.
Overall the place is good, but it has some improvement points.
