Alberto's place is great! The flat was recently renovated, it's very clean and beautiful. It's also not far from the Metro station from where it's easy to reach either the center or the EXPO.
We were welcomed very warmly by Alberto's mother in law as Alberto wasn't in Milan that weekend. It was nice chatting to her and she explained us everything we wanted to know about Milan or public transport or parking (you can park your car for free in the street just in front of the house- very quiet area).
All in all we really enjoyed our stay. Thank you very much
