Giovanni's place is really wonderful: spacious, luminous, decorated with very good taste and fully furnished/well equipped. It's located at a walking distance from main touristic attractions, notably il duomo and Vittorio Emanuele gallery. The neighborhood is very lively, but at the same time the apartment is quite calm -- the room faces the inner garden of the building so there's no noise that can disrupt sleep.
Also, Giovanni is super nice, very responsive, helpful, and friendly.
I'd recommend this accommodation for both working and pleasure trips.
