I was in Milan for a month for work, and picked Giuseppe's apartment for my stay based on the other reviews, the price, and the location. It was the perfect size for me, including a separate bedroom, nice bathroom, and a small kitchen which is perfect for cooking. It's conveniently located near the Dateo station (which you can take in 1 stop to the Red Line for example), and also convenient to many bus lines, which give you good access to the city. There are many grocery stores nearby, from the small Carfour Express around the corner (which actually has most everything you need) to the much larger Esselunga a few blocks away.
Giuseppe is a great host and was very responsive for the few (minor) issues that cropped up, and got them fixed quickly.
I will definitely hope to book Giuseppe's flat next time I'm in Milan.
