Nicoletta was a great host for my family and I. She was very responsive and helpful. She let us checkin an hour early and greeted us at the apartment. Any questions that we had, she provided helpful answers.
The apt isn't that far from the city center. I would say 'maybe' a 10 minute walk(if that) from the train station. Counting me, there was a total of 4 people staying at her place and there was plenty of room.
If (and when) I come back to Florence, I will look to stay at one of Nicoletta's properties again.
