I stayed here for 10 weeks from Nov - Jan. The apartment was absolutely great for a long stay. It is in a terrific location near the station, the market, and the historic centre and yet the street it is on is nice and quiet.
The apartment is larger than it appears in the photos and has everything that I needed. The kitchen is well equipped, the bathroom is nice and the terrace is a great bonus.
Ferdinando was responsive and helpful and checking in and out was simple.
I would heartily recommend this apartment and would definitely try to book it again the next time that I am in Florence.
