Same Hipotecario ATM - no issues withdrawing with international cards.

NBC ATM near the entrance of Kendwa Rocks Hotel in Tanzania worked smoothly with both Visa and Mastercard. Felt totally safe at night.

Commercial Bank ATM was in an air-conditioned area-nice touch!

HypoVereinsbank: if the ATMs are broken and you need to go to the counter for cash, prepare for a long wait.

BNB ATM was in poor condition - dirty and not confidence-inspiring.

Arion Bank is solid - usually feels safe. Everything worked as expected.
