The Santander ATM located at BOS Terminal C, 100 Harborside Dr, Boston, is easily accessible within the terminal area. Its placement makes it convenient for travelers needing quick cash before or after flights. The machine is straightforward to use, with clear instructions for withdrawing cash. However, some users have noted that the ATM can be a bit difficult to spot initially due to its placement among other terminal facilities. Overall, it serves its purpose for those in the terminal, but the visibility and signage could be improved to enhance user experience.
