Apartment is great! The most important for our stay was it's location. It is less then 10 minutes to railway station what is very convenient, because we used train a lot to explore another cities in Tuscany.
It is also 10 minutes to city center.
Another thing is that apartment is very clean and you will find there everything you need for your stay. For example, there are some spices, even coffee.
Alessandra was very helpful and gave us all information we needed. She even gave us some touristic maps and guide.
We felt very comfortable in apartment and it was four of us. I recommend this apartment for your stay in Florence, and I would stay there again definitely.
