Very good choice.
Apartment is modern, well equipped and spotlessly clean. I can speak only highly of it!!
It is very well located, just couple of minutes from the T2 Tram terminal stop (the best airport connection), and after a few meters you are by Duomo Cathedral.
As the apartment has self-check-in option, it is easy to get there any time.
Barbara is very good host. She is communicative and able to help with all the things you need to know.
If I am in Florence again, I will choose this apartment again!!
