During our trip in Italy (Pisa - Cinque Terre - Milan) we stayed for 3 nights at Andrea's place. It's the perfect place to come home to after exploring Milan's city life! Andrea is a very nice host and made us feel directly at home.
As said in other comments, the view on top of the terrace is spectacular and is probably the best place to consume some wine and Italian foodies in the whole of the city :)
The appartment is clean, big and very 'arty' decorated. Lots of books, paintings, art,....
To conclude: without doubt the best place to stay while being in Milan!
