Andrea's place is amazing. It is full of little details you may study for the longest time. I think even if I were to be locked in the apartment without any way out for the duration of my stay, I'd still had something to discover every day.
We did a family trip to Milan, and I had my reservations about staying so close to the most lively area of the city, but the inner courtyard is very silent and tranquil, and closed windows on the facade would prevent any noise coming through — we had excellent and uninterrupted sleep every night.
The location is excellent, especially if you like nightlife. We rarely used public transport when our destination was in the center of the city — everything is in the walking distance.
Andrea is a wonderful and helpful person. We had our flight delayed for 12 hours and he did his best to meet us even at midnight. Afterwards he was quick to answer all our questions.
