Pros: The location cannot be beat! I visit Firenze often and it's a wonderful location walking distance to stores, restaurants and other attractions in the Oltrarno area, but also close to the historic center. The description and pictures are accurate, and the apartment is comfortable. The communication with Pierpaolo was good, over all.
Cons: The noise. Firenze is a noisy city in general, but the street is particularly loud because it has ample parking for scooters and is located next door to a parking garage. Also the last day my stay there were renovations in the next door unit, which compounded the noise considerably.
Overall, it's a safe, clean apartment in a great location . But if you're a light sleeper, bring your earplugs.
