The apartment is very nice, big, located on the small and not noisy street. It is the big and warm flat on the third floor (it is not the basement and not the loft as we can frequently see on Airbnb).
Giulia met us personally and showed the apartment, she was very polite and gave us some useful tips.
Location is pretty good, there are a lot of cafe and restaurants around. All historical places can be reached on foot. Boboli gardens are very close to the house. The railway station also not very far from flat, 20 minutes on foot.
The apartment looks like on the photo. Well designed, modern furniture in excellent state. The bed is large and comfortable. Good windows that isolate the noise. Heating works vary well (we were in winter). Good bathroom with washer machine, hot water. The kitchen is equiped well, there are all necessary dishes, stove, fridge, but there is no microwave.
That was nice to find and look several art albums about Florence.
In general our stay was very comfortable and nice.
