We were met by Alessandra for check-in, who gave us the most thorough walk-through of an Airbnb I've ever experienced. Very casual and amicable. She was kind enough to answer my questions from the mundane to the cultural to the linguistic. Only wish I had asked her more questions. Her replies were also nearly instantaneous whenever we needed advice/info on Whatsapp (this we were most thankful for when we needed to go to the police, and she immediately directed us to the nearest location)
As for the apartment itself, it's a spacious open loft on the 2nd floor (aka, 1st floor in Italian) above the lower shops/restaurants after two sets of wide stairs. Kitchen is equipped with cooking/eating utensils and basics like oil, balsamic vinegar, salt, pepper and whatever dried goods past guests have left behind and of course, coffee. Strong wifi, decent water pressure, good drainage in shower. One queen bed and small daybed downstairs, with futon and twin beds inside partitioned loft upstairs. It's probably ideal for a family with teens or small children. Otherwise, if you are a set of adult couples, do consider that although there is some partitioning, none of the sleeping areas have absolute privacy (you won't see each other once in the rooms, but you will hear one another easily).
Location: less than 10 minutes walk from the train station. Right around the corner from Mercato Centra/San Lorenzo Market so you'll hear traffic in the morning as shops and people start to set up shops downstairs and nearby and will hear chatter late into the night. It's great if you want to experience the lively sounds of a busy area, but if you're a light sleeper, bring earplugs.
Although I didn't get to meet Tiziana, you can tell she prides herself on being a host. Her house manual is thick with all kinds of city information and personal recommendations. In addition to that, there are all sorts of brochures and business cards strewn about in corners. No need to go to a tourist info point beforehand.
