Massimiliano is a typical Italian (meaning welcoming, open, friendly and likes to drink good coffee ;) ). I enjoyed my stay, as the room is spacious, the bed is cozy and the area is interesting.
I am sure the bathroom was mentioned already - I would consider it the first of possible sightseeing stations in Milan, as Massimiliano (artist he is) put quite some effort and affection into the decoration of it (okay - it certainly isn't for the faint of heart, but interesting for sure). His space is nice and cozy, you can relax and plan your day trips.
What I liked is that he offers breakfast - and if you like to go out, you can easily eat as well in the enclosed compound in the Cafe at the gate. In the evening you can have excellent soul food and draft beer in the cozy eatery at the gate.
Going into the city center is easy - either right there taking the bus 38, or crossing the bridge and using the 54 to go straight to the Duomo, with a day ticket for 4.50EUR.
All in all, I can only strongly suggest to stay with him to enjoy some relaxed days in Milan.
