Bulgaria is one of the few European Union member states that still uses its own currency – the Bulgarian LEV (BGN) with a currency rate of 1 EUR = 1.95 lv.. Be careful when going to a CHANGE bureau. Check the exchange rates in advance and look for a sign with NO COMMISSION.
Avoid changing money on the airport and in hotels because you will not get the best rate.
Cash or credit?
Make sure you always have a bit of cash along as small shops and restaurants may still not be equipped with a pos-terminal. The same applies to any kind of street shops and small bakeries.
