The apartment was in an excellent location to walk to many of the sites in Florence.
It would be a challenge for anyone with mobility issues, as there is a relatively steep hill that needs to be climbed to get to the main door of building and then 3 flights of fairly steep stairs to get to the apartment. Vanni advised us to take a cab to the apartment so that we wouldn't have to drag our suitcases up this hill.
There is a mosquito problem as well. If you open the windows that don't have screens, it lets in mosquitos that seem to congregate in the sleeping area. Vanni did warn us of that, and provided us with some plug in mosquito repellent (this worked if you don't mind breathing in the chemicals used to repeal the mosquitos while you are sleeping).
The washing machine is a nice addition, however, our clothes didn't dry on the drying rack provided as it had rained and the air was humid.
