We stayed in Niccolò's place for 3 nights in mid October. It's a very nice apartment. Unfortunately we didn't get to meet him but his friend Simone met us at the train station and walked us to the apartment and explained how everything worked. It's in a really good location, only a few minutes from central and the Duomo. There are plenty of nice places to eat near by as well as markets. The apartment itself is very nice, but as its on a main road, can be a bit noisy at night. Would recommend staying here.
