Roberto is an amazing host, polite and helpful, on hand whenever I needed him. The apartment is beautiful, very clean and comfortable, and very quiet even if located in one of the "coolest" areas of the city (the view from the balcony access is awesome.... go and check it!!). It's very easy to reach the place, since the Porta Garibaldi subway station is really close. I'm very satisfied and I think that I'll look for Roberto's apartment again, for my next trip in Milan!!
