We have the opportunity to stay in Paola's apartment and the experience was really recomendable. The location of the apartment is just two minutes walking from Santa Croce square and all the main attractions in Florence are accesible by walking.
The area is also plenty of restaurants and bars.
Unfortunately we couldn't have the opportunity to meet Paola personally, but this was not any problem, since she was always accesible by mail and phone when we needed.
We stayed in Firenze in January and it was specially cold outside but the apartment was conveniently warm.
We recomend everyone to stay in Paola's.
