The location is amazing, and the bed is very comfortable. There are lots of very thoughtful details in the decoration.
The house is actually a little odder than it appears in the pictures, and while there is a kitchen I would not recommend planning on cooking anything complex in it.
The stairs to the bathroom are quite steep, and would not be good for someone who has to use the bathroom at night and was not very stable.
For us it was an excellent place to stay for a short adventure in Florence. The restaurant il santo bevitore across the street is fantastic, as is the gelato on the corner.
