Lucio's appartement was amazing to stay at and I can highly recommend it.
Lucio welcomed us warmly at the appartment at the agreed upon time (even though we ourselves were a couple minutes late) and all communication went smoothly.
The appartement itself is clean and it's perfectly soothed for 4 people. It's located close enough to the duomo and the surrounding shops (about a 15 min walk to the duomo). If walking does not sound appealing, there're trams that stop nearby that will bring you to the duomo (at the time of writing this review: trams 12 and 19) and to the castello and teatro dal verme (tram 19) in no time. Also, there's no shortage of restaurants near the appartment.
If you're going to Milan, you should definitely consider staying here!
Thank you Lucio for letting us stay at your wonderful appartment!
