Andrea's apartment is beautiful, modern, clean and at a very convenient location. It is a stone's throw away from the Duomo. There are elevators, which are very convenient when you have heavy luggage. There are floor to ceiling windows which really maximizes the city view.
Andrea was also very helpful, making sure to greet me when I arrived to walk me through how to get to the apartment and where everything was. The guidebook in the apartment itself was also helpful and can answer practically every question you may have.
Would definitely stay in Andrea's apartment again the next time I am in Milan.
