The location is a 7 minute walk from the Duomo. Just marvelous! We enjoyied our stay, but the place was not that clean, rather dusty.. and the bedding did not feel fresh. Also, lots of mosquitos. On the other hand, the hosts are sweet and very communicative, they gave us a list of places to go to while in Milan.
Tip: follow the photos attached by the hosts. Do not look for the address on google maps as it will lead you in the wrong.. wrong place.
