Everything turned out great in Bianca's apartment. The location is just perfect, 10 minutes from the train station and just 2 blocks from the Duomo... can't beat that!
As for the apartment, the instructions to get in were very accurate and we didn't have any kind of trouble with them. The apartment was awesome, and they took the trouble of leaving us coffee for the breakfast, as well as everything for the bathroom and beds. They even left us a bottle of wine!
The communication with Paola, Biancas daughter in law, was perfect.
We certainly recommend this apartment to anyone going to Firenze!!
