Great stay, the host is super nice, respectful and responsive and made me feel at home which was the great plus. I never took the metro as the location is quite central. The apartment is kept very clean and wifi worked well which was important for me as I worked from home.
My tips: there are great cafes (Lodetto) and bakeries (pan do kilo) around. If you are sensitive to street noise at night: earplugs! And also get some warm clothes as the room is big and the mini heater in the room not super efficient.
