Ginevra - and her mother! - are warm, helpful hosts. They gave great recommendations for Florence, including sights to see and places to eat. The listing was clean, quiet, and comfortable, with solid amenities - can't stress enough the importance of laundry and good laundry detergent! - and a great location, within walking distance of a wonderful food market and the Piazza Della Signoria. As a solo traveller I had more than enough room.
The only thing I will note is that the room is quite dark, with functionally no natural light during the day. This is totally fine for a short stay, when it's easy to spend the whole day out sightseeing, but for a longer stay (when you might want a rest day inside, or to get some remote work done), it can be a little much. Thankfully there's a nice library a short walk away where you can work with a great view. :) Ginevra was really understanding and flexible when I adjusted my travel plans, too.
