Small apartment at a 20 minutes walk from Navigli. The apartment is nice, at a 15 minutes walk from the metro and next to the tram stop which will get you to the center. It is reasonably well equipped but not as clean as I would have liked.
If you only book the twin bedroom, you will not get access to the entire apartment (living room will be locked). This includes the table, so you will get a kitchen to cook but not the table to comfortably sit and eat. there is a VERY small table in the kitchen in which personally I don't fit.
The hosts tried to change our checkout hour from 11:00 am to 9:00 am which is a big cons. I don't think I would really recommend this place to other people.
