Biancas apartment is fantastic! It is the Airbnb place I enjoyed most of all my trips! The rooms are lovely and the view from the terrace is amazing. The apartment is located in a 7-8 min walking distance to piazza Dante, which is at metro line 1.
Bianca is very nice and helped me to have a great stay by explaining to me how to reach places I planed to visit and organised a privat transport to the bus station early in the morning.
