Best way to pay and withdraw cash in Istanbul as a tourist

Currency exchange at hotel reception can be unreliable: cash isn't always available immediately and may be handed over in installments over a day or two.

Small USD bills are accepted almost everywhere for exchange or payment, but a $100 bill may be refused in shops if the vendor realizes you're there to exchange money rather than actually shop.

Some tourists exchange currency through their local tour guide, with reportedly decent rates as an alternative to exchange offices.

For everyday spending in Istanbul, it is safer to rely on Turkish lira: recent reports say supermarkets, small shops, and bazaars often do not accept foreign cash.

If you pay tour operators or tourist-facing businesses in euros or dollars, check the change carefully: they may hand back older US dollar notes, which can be difficult for a tourist to exchange later at a normal rate.

Letim service works well for payments in Istanbul: you can withdraw cash from ATMs and pay via QR code at major retailers. It's cheaper and simpler than the typical multi-step currency exchange chain.

Large retail stores like Vaikiki accept USD or EUR and give change in Turkish lira, often at a better rate than currency exchange offices.

Paying directly in USD at shops and cafes is another option that works in many places across Istanbul, though the exchange rate may vary by vendor.
