Visited Milan with my wife and 2 daughters (10 and 12). The apartment was spacious and clean with lovely high ceilings. The girls fought over their rooms (double v single) but that was their only argument. The Duomo is 15-20 minutes on the tram (5 minutes walk to tram). We can recommend La Gravina for a meal or takeaway- fantastic pizza at reasonable prices. Pansi and Jacobo were great hosts and even ordered us a taxi to get to the station.
