Massimo was a great host who works well to make things easy for his visitors. He responded quickly and said that he himself wouldn't be able to meet me when I arrived but that his wife would meet me and give me the keys. Massimo's wife was very kind and helpful.
Massimo's apartment is located greatly. It's a 2-3 minute walk from the Loreto metro station and the exit Piazza Argentina. Loreto is both close to the duomo and the San Siro stadium which are the most important things for me to visit in Italy.
The area is filled with great restaurants and I can really recommend the fish restaurant Delfino which is located nearby.
The apartment itself is cozy and clean. I will surely give Massimo a call when I go back to Milan.
