This apartment is ideally located and very clean. All sites in Florence are 5to minutes walking , and the nearby taxi stand was very handy when we had to go to the train station.
All the windows are sound proofed so that, while it may be true that the location can be noisy because it is so central, all sounds can be eliminated for easier sleep.
Marina also provides a very useful manual that she has obviously taken a great deal of time to prepare.
I would highly recommend this apartment with one small caveat, there are a lot of steps (57 by my count), so consider this if you have heart or knee problems.
