u/MagicianUsed9545

I'm going to Bosnia in a few days and had read that most places accepted cash. I currently have £200 in cash, should i change it to euros while I'm still here in the UK or should I exchange it at Sarajevo airport? This is for taxi payment to go to my Airbnb! Heard that it's not recommended to change it at the airport due to it being expensive. And I was planning to change most of my cash to BAM in Old Town later AND also heard that they also charge extra on pound compared to euro? (idk if this is true but that's what i read from facebook and reddit)

HELP ME PLEASE
