I was staying at Roberto's place for 4 days with a friend. The check-in was very fast and unproblematic, as Roberto is really welcoming and helpful. Just prepare all the questions regarding w-lan, check-out, proper location of the flat etc. in advance though. This was not really discussed by Roberto, and as you're talking and just arriving these stuff can easily slip off your mind.
The flat is located in China Town, which can be easily reached by public transport, and also gives you a different side of Milan.
While the flat looks pretty much the same as in the pictures, the furniture is very used. The door handle came off, and the area to put the key in was also falling apart. Also, we were only provided with one blanket for the two of us.
