Luca's apartment is in a very central location. Being <5 mins away (about 2 blocks) from the train station was great because I had early trains out of Milano. Being that close to Centrale also meant you had access to all 3 lines of subways which made getting around the city incredibly easy. I appreciated that the apartment was so clean and stylishly decorated, and that there were umbrellas to borrow! There is a washer/dryer combo in the bathroom but it doesn't dry well (as most dual machines don't). There's also an elevator that takes you to the second floor where the apartment is located.
As a host, Luca is amazing. He was in communication every step of the way and made sure I had everything I needed, like blankets when it was cold. (There is heat but apparently by Italian law you cannot turn on until Dec 1)
For light sleepers like myself, you can hear noise from the courtyard because the windows are thin. I could overhear loud conversations from other units, especially if their windows were open. However, I found with white noise and earplugs, I was fine.
Would recommend to anyone who's looking for a clean and safe experience that is very close to the Milano Centrale station!!
