Marco definitely warrants his Superhost designation. He puts a lot of effort into making sure that the place is spotless and welcoming when his guests arrive, and also makes a point of being there to greet them himself.
My wife and I were wrapping up our honeymoon in Milan after a week of traveling throughout Italy, and Marco had a bottle of champagne waiting for us when we checked in, in addition to all the other amenities he offers. He made us feel at home more than any other Bnb host on the trip did, and they weren't all bad either.
The only issues I would point out are both out of Marco's control: there's a tram stop located literally downstairs of the complex that runs pretty late at night (it didn't keep us from sleeping but it might bother lighter sleepers), and the elevator in the complex is pretty old fashioned and therefore on the scary side. But I took it a few times and I'm still here to type this review, so obviously nothing happened to me.
If you don't mind a bit of a walk to get to the city center, definitely give Marco's place a try. You won't regret it.
