We stayed 10 days in the apartment and it was a great stay! The location is perfect, close to all attractions but outside of the busy touristic places. The communication for the arrival was not optimal because I did not hear anything from CleanBnB until the day of departure, but this did not cause any problems. Lorenzo was very kind during our arrival and took his time to show us around and give some tips.
The apartment is very spacious with good facilities such as a comfortable shower, big fridge, large stove, and two good airconditioning units. The bed was decent, the neighbourhood can be a bit noisy but with the windows closed it wasn't a problem.
The only downside of the apartment was the cleanliness. The apartment was quite dusty and the cutlery and dishes were old and not very clean either. We had to clean them ourselves before using. It was nothing major, it just felt a bit off. It would be good if a new pair of cutlery was bought for the new visitors.
I would definitly recommend this apartment for visitors of Florence, especially for a longer stay. It will feel like your temporary home on vacation.
