I'm glad we stayed at Omar's place. On our little northern Italy tour, we only had a few days in Milan so the location is important. Omar's place was a great base. The tram 14 and 19 stop only 50-100m from his door. They take you to the Duomo, the Expo and the other main places and they run past midnight. Also, Omar was very helpful in giving us the tips we need. He gave us a brillant two-page document with restaurants and gelaterias that he found to be good. This saved us a lot of time and frustration. Good stuff.
