My wife and I stayed here for 4 days whilst on our honeymoon. Nicoletta met us for checkin, and was very warm and welcoming: a welcome which included a bottle of Prosecco!
The apartment is in a quiet area, has been recently renovated to a beautiful standard, with all the creature comforts of home including two air-conditioners, which was great as it's quite hot in summer! It also has an inward facing balcony over gardens, on which we enjoyed a peaceful dinner one night.
Both Francesco and Nicoletta are very passionate about Florence and the Tuscan region (Franceso is a wine producer in the hills), with lots of information and enthusiasm for places to see, do and eat at. They're two of the nicest people you're likely to meet. We highly recommend their apartment for a stay.
