I stayed in this apartment for 5 weeks and it was great: perfect location in the center, gorgeous panoramic view from the living room, absolutely everything needed for living and very nice landlord Alberto who was always ready to help and suggest. The apartment is in historic building, with very florentine spirit: huge door, amazing chandelier near the entrance. In the apartment furniture is modern, neat, nothing superfluous. As the location is central, there are plenty of restaurants, cafes and shops...and there is Laduree in the nearest building, so possible to enjoy best French sweets :)
Definitely i can recommend it for short or long stays, it is perfect to feel yourself like at your florentine home.
