Barbara was very helpful and had great suggestions of where to go, such as to visit the gardens and palace nearby (which we did), and where to grocery shop (very close to the apartment).
The apartment is small for a family of five. Though the beds are very comfortable, the space in the apartment is small. The bathroom in particular is very small. During our three days in Florence, we did not have any hot water for two of them. Barbara said this has never happened before, so it must be unusual. But for 5 people to not have any hot water for showers or dishes was very in inconvenient.
Barbara is very quick to respond to email, and was able to answer all of our questions during our stay. We liked the location (very close to the museums and everything). The only major issue for us was the water and the small bathroom.
