The apartment is a five minute walk from the central train station, which worked great for us as we only stayed in Milan for one night. The Duomo area is easily reachable by metro and is 4 stops away. The apartment itself is exactly as described, clean and well stocked. The air conditioning worked great which was a huge benefit in the summer heat. The apartment is on the fourth floor with no elevator, Giorgio helped us with the luggage during check in.
The area around the train station and the building itself are a bit sketchy, but if you're looking for a good apartment in that area, this is the one for you.
