Pros: Very modern and good location. Host was very helpful and kind. Washer and dryer for clothes was very useful.
Cons: A little noisy, since in the heart of Florence, which is expected.
We had a one bedroom apartment, if you are more than 2 people, you'll have to use the sofa bed, which is not very comfortable, and makes the apartment very small/constricted.
General info: no room cleaning/room service, since not a hotel.
