If you are looking at this review then STOP and make your booking today. You will be delighted you did. Barbara is brilliant, speaks English fluently and her home is elegant and exactly as you see in the photos.
Florence is a beautiful city and having Barbara as your hostess is better than the best as she is able to talk on navigating the city easily, places to go, great bars, food to eat or avoid and of course she knows the history of the city better than any guidebook including the art, architecture, the Medici family, politics, the best views of Florence, etc. It's an education and a joy and why you should NOT miss this opportunity to experience her natural incites, Italian charm and the perspectives from a native Florentine.
Cheers and thanks for having me.
