I have been using AirBnb for a few years and this is easily by far and away the best place I have ever stayed. If it is available book it right now, it will be a big mistake if you don't.
the location is perfect for sight seeing in Florence. it is about a 5 minute walk to the city center and very close to everything. the actual apartment was spotless and had coffee, tea, cereal, etc. and Laura (Gianfranco's daughter) had even got some of the best cookies in Florence for us.
However this all paled in comparison to the hospitality shown by Laura. She is super communicative and seems like a terrific person. She sat down with us and mapped everything out, told us all the places she recommends for food, gelato, sight seeing etc. All of her recommendations were spot in and she truly made our trip to Florence a million times better. My mother even was sick during our trip and she helped set everything up and was very amenable to our situation.
Again, I can not say enough of how much better our experience was. I have never experienced this type of hospitality from an AirBnb host and it would have been a huge mistake to not book this place.
Do yourself a favor and book now.
