We stayed with Maria for the second time already, and loved it, again! The location is fantastic, by the vibrant Navigli canal, and only a 20 min walk to Duomo. All the metro and other connections are close by as well.
The condo is cute, small, but nicely decorated and organized. I love that the windows are of a good quality, so that you don't hear any of the happening on the street. We are already looking forward to our return.
