As far as I know there are only three ATMs/cash machines in Guardia Sanframondi. See below for photographs and directions.
 The westernmost ATM in Guardia Sanframondi. To find this one, walk west along the Corso Umberto from the town centre. It’s on the left just beyond La Tana dell’Orso on the right. |
 The most central ATM is at the post office. The most central ATM is at the post office, behind the Municipio. |
 The easternmost ATM in Guardia Sanframondi. The easternmost ATM is on the right as you walk east, away from the town centre, along the Via Municipio. |
