We have stayed in Florence (Firenze) many times over the years in hotels as well as apartments. This, by far, was our best place we have ever stayed in Florence. Location was excellent, access to train, bus, walking within city center was so easy since we were staying there; the staff was great, walked us to our apartment, showed us how the heating and cooling system worked, answered questions, etc.
This group of apartments is at the top of our list for future trips.
