We had a terrific stay in this apartment. It is spacious, clean, comfortably furnished, and easy to access. The beds were very comfortable. The WiFi is blazing fast (146 Mbps down, 19.8 up).
It is also close to transit, one block to closest bus stop (but we had to walk farther due to road construction), plus a few nearby restaurants/cafes and a grocery store (2-5 blocks).
The hosts are fantastic and very helpful.
The neighborhood seemed safe and easy to navigate. Easy bus rides into central Florence. Really the only down side is that the trash receptacles for the block are directly across the street and so we got to hear breaking glass at all hours of the day and night.
We would definitely stay here again!
