We had a wonderful time in this apartment. It's very comfortable and cozy with lots of details such as books, dvds, candles, etc. We especially liked the blue ceiling with stars and a moon that glow in the dark! The kitchen is fully equipped and provides everything needed for cooking.
The apartment is perfect for two or three people, but even four people would fit. It's located in a very nice neighbourhood, you can walk by foot to Navigli (lots of nice bars and restaurants). A big supermarket is nearby, also a tram station that takes you to Duomo directly.
The contact to Andrea (and Massimo) was easy. We were surprised how professionally everything was managed, there even were linen and towels fresh from the laundry!
All in all, we felt very comfortable in this apartment and would highly recommend it :)
