Caterina's apartment was a great home base for our few days in Florence. It easily fit a family of four plus an infant. The location was great and central to everything you want to see. The only downside to having such a central location is that it could get a little loud sometimes.
Caterina and Filippo were great hosts and very accommodating - she even sent someone to help us out with the thermostat. We could happily spend many more nights in class Caterina exploring the beauty of Florence.
