I had a wonderful stay at Fabio & Irene's house, and it was very sad to leave.
First and foremost, Fabio is a true gentleman - very open and friendly, yet respectful of the guest's privacy. He welcomed me with great energy and walked me through the amenities of the house.
About the house - I could see how Fabio and Irene really thought about the guests' comforts and needs - there is everything you can think of - from coffee, and simple croissant to iron, kettles, and umbrellas, the house is fully equipped.
About the location - Galluzzo was perfect for me. It only takes around 7 minutes to get to Oltrano (my favorite area) by bus, but then I got to enjoy the quietness when I got home. Also, if you enjoy walking and visiting the less-beaten roads like me, you can even walk to Arcetri from Fabio's place! As a female solo traveler, I found the area very safe even during late evening.
Highly recommend Fabio's place!
