Cristina is the ultimate host. From the beginning she was prompt in answering my emails. She was punctual in meeting us upon our arrival and kind enough to arrange our taxi at the end of our stay.
We had low hot water at the beginning, but she and her husband were there in minutes to solve it with the flip of a switch.
The layout of the apartment - two bath and bed combinations - makes it perfect for two singles or two couples. In addition, there are two roll out beds that would work for kids. Although we didn't cook at all, I took note that the kitchen was well outfitted.
The location of the apartment couldn't be better; with Piazza Della Signoria virtually outside the door, Rivoire is your local coffee shop. (Be aware they close on Mondays!)
I highly recommend this apartment and Cristina.
