Most shops open at 9:00 and accept visitors till 19:00. Large shopping centers may work until 21:00 while supermarkets and food stores often work around the clock.



The national currency is the Bulgarian Lev. Bank notes of the following denominations are in circulation: 2, 5, 10, 20, 50, 100 Levs. 1 Euro = 1,95583 BGN.There are numerous foreign exchange offices and ATMs around the city centre.

It's always prudent to carry a little foreign cash, however, in case you can't find an ATM or bank office nearby. You can always change cash at the hotel, though the commission will be high.

Make sure you have enough of the national currency when you plan to visit local markets and shops.
