Marcos apartment was great. The location is perfect. Not far from all the sites and restaurants (especially Duomo) and very walkable from the train station (between 5-10 minutes). The apartment is very clean, wifi worked great, air conditioner worked just fine and a bottle of wine was left for us. Google maps doesn't take you to the correct spot but no worries because Marco met us where he figured we would end up. It is up a few flights of stairs so the initial baggage haul takes some work but it is well worth it. Also, Duomo at night is quite a view.
