FLorence is far form Pistoia 30km, 15minutes by car and 30 by train; and is very expensive.
If you come by train we are avaible to get you at the station.
I you come by car, at the exit for Pistoia, turn on the right ad you find a traffic light, turn on the right, 2 km and you find the B&B. Ask for 'Ponte Stella' and 'Cioni Family'.
