Besides checking the availability, limits, fees, IDs, onboard ATM cameras and such with site such as CoinATMRadar, and then verifying the information by contacting the locations via their contact details, I’d also consider looking for a place with various Bitcoin ATMs in a reasonable range, lest you were to encounter some unexpected issue with the chosen ATM location.
One thing that would bug me is the safety of the location itself. I’ve seen some photographs of some ATMs that seem to be placed in a junkie parlour, certainly a profile to avoid.
