Paola couldn't meet us but her son Filippo was there to welcome us. The apartment was very clean, and matches the description and pictures. It is located near everything and all the monuments and museums, supermarkets and restaurants are within walking distance. The apartment has a florentine charm that makes the experience more real.
The only thing is that the stairs are very steep (it's an old, charming building) so if you have any problem with your body it may be difficult for you to get up to the apartment.
I recommend staying at Paola's apartment!
