The space: Lots of amenities, it was great having a full kitchen to cook in. The space was also very quiet and comfortable.
The location: close to the major attractions, (15 minute walk to the duomo), but far enough away and on a residential street so you're not surrounded by hordes of tourists.
Michele and his family were gracious hosts and had lots of great tips for the area too. They were also flexible with check in and check out.
