The apartment is close to the main tourist area and the train station is walking distance too. And also we found out nice restaurants near the apartment.
The rooms are charmingly decorated with some pictures and antiques. The well-equipped kitchen and the bathroom are very clean.
Unfortunately we had no chance to meet Irene and just met her father, but she replied soon when we ask something via text.
So I think it is a perfect place to stay in Firenze!
