I really enjoyed Lucia's apartment. It's in a safe area of Milan and the city centre is not far at all. I found the apartment easily, it's close to the metro station (that takes you to Duomo). There are a few reastaurants (e.g. one next to the metro station) and there's a supermarket that you can reach within 5 minutes on foot.
The apartment itself is modern, very spacious (for 3 people), comfortable and well-equipped (with wi-fi, air conditioner and hairdryer).
Communication went very well, Lucia always responded quickly and it was no problem to check-in later than 20:00.
I recommend this apartment!
