All in all, this was perfect! I am planning to eventually return to Florence and will do my best to be staying in this house when I do.
I had an enchanting time when staying at Alessandro's!
The room is very spacious (bigger than it looks on the picture) and his house is full of character, an old convent with high ceilings and murals, located right on the via Faentina in the north of Florence, a short walk away from the centre.
The place is clean and tidy, with a well equipped kitchen and a bathroom with walk-in shower, and I enjoyed the small outdoor sitting area at the back where I could have a cigarette with my coffee in the sunny mornings. Alessandro was most helpful and attentive, and he knows his city through and through. He is friendly but never intrusive, he speaks English and will no doubt be able to suggest original outings during your stay, away from the tourist crowd.
