This apartment is in a great location. You can easily walk to all the wonderful historical sites in Florence. Plus plenty of shopping and restaurants nearby. While the apartment is on the 2nd floor, just be aware that there are two rather long flights of stairs to go up to get there, especially if you have lots of luggage.
We parked our rental car at Parcheggio Beccaria which was about a 15 minute walk away outside of the restricted driving area in the city center. Communication with Caterina about where to park was a bit difficult due to the language barrier.
I would recommend this place as it is conveniently located and the apartment while rather old has "Italian" charm. The master bedroom is quite large and there were two bathrooms, plus a kitchen that appeared well equipped and a living/dining room. While we were only there one night, it was quiet in the area overnight.
