We had a great stay at Moscova appartment! The location is perfect if you want to visit Milan walking (15 min walking to the Duomo and the historical center). No need to take the subway!
The neighborhood is very dynamic (many restaurants, bars, etc).
The place is good for 4, but it might be a bit tiny if you want to cook at home.
We would totally recommend Moscova appartment for a coule or a small group of friends!
