The apartment is a really cute studio located very very close to the train station and the central parts of Florence. While it is centrally located, it is tucked into a wonderfully quiet area so there is no noise at night like the other areas. Location wise this place is unbeatable.
The only issue we had was that because the loft is on two levels with the bed being on the upper level, the AC did not cool the whole apartment. We really struggled to sleep (we prefer the temperature to be quite cool but if this is not a problem for you, then it should not be an issue).
The other thing I will say is that most airbnbs I have stayed at previously have usually provided a few amenities like travel sized soaps or shampoos. While this is not at all a requirement from a host, this place felt quite basic (not above and beyond). Not a bad place to stay but you get what you pay for.
