We stayed in this apartment in July 2022. Exactly as advertised. Separate room with queen bed and pull out. Slept 4 comfortably. Single bathroom. Washer, coffee maker, iron, towels, AC. Very secure. About a 5 minute walk to Duomo, Galleria and Opera House. Many shops, restaurants, bars and markets nearby.
As for the 30 minute check-in procedure that people discuss in the comments, it is true. However, Marcus cares about his property and is charming and funny. We actually enjoyed his jokes and a little history about the building, Milan and DaVinci. He also helped us with restaurants (the place next door (Rossini) is amazing!) and options to get to the airport. I would highly recommend this property.
