Although the national currency is the Lev, it is usual for property transactions to be advertised and completed in Euros.  The Lev is tied to the Euro at a fixed rate of 1 = Lev 1.955

With the exception of some larger establishments in Sofia, credit and debit cards are not universally accepted and cash remains the preferred currency.  However, ATM’s are becoming increasingly popular where the above cards can be used to withdraw cash.  Money can also be exchanged in bureaus and banks. Leva notes dated 1997 and earlier are now out of circulation, but unscrupulous money changers may offer these, as well as advertise misleading exchange rates, so it is advisable to only use official outlets.  For ATM locations, see:

The import of foreign currency is unlimited, but amounts over 8000 lev (or equivalent) should be declared on arrival.  Export is limited to the amount declared on arrival. 

Banking hours: Mon - Fri 0900 - 1600.
