Francesco's place is so spacious - we had a great time. It's extremely convenient, being roughly equidistant between the train station and the duomo/city centre. It's also well equipped if you fancy a home cooked meal (as we did one night).
Francesco was also extremely accommodating. When our train was due to arrive early, he arranged for the apartment to be available earlier than usual. He also sent very clear joining and leaving instructions, and everything was extremely smooth.
Several comments say that the apartment is noisy at night. It is on a busy road, so some noise is unavoidable. But in general we didn't find the noise volumes were problematic and it certainly didn't keep us up at night.
