Apartment was great and in a very good and central location close to the major attractions and the SMN train station and subway access.
Two upstairs bedroom suites (with their own bathroom) and a downstairs lavabo makes it easy for a family to wake up and dress quickly making your available daytime longer.
The living room is large and has an area for a 4 person dinner/coffee table. Air conditioning and kitchen major appliances are available. Only missing items for us (having a long trip), were a washer and an iron.
A couple of issues that could be better are the bath water temperature control that is difficult - there are plenty of hot water but temperature needs to be adjusted constantly and and had one circuit breaker that triggered when we turned the dishwasher, quickly solved by a contact with the host (just happened once).
As a host Margheritta was very good and responsive helping us in the check-in process as well as helping us to call a cab when checking out.
We had a wonderful time at the apartment and we recommend it to anyone looking for a great (and central) spot in Florence. We will look to book it when we return to the city.
