Im off to bororvets on the 19th as well, I have been advised to take sterling, but it also advises there are ATM's around so you can draw out cash on your Visa / Visa delta
Where are you stopping, my and the lads are on our first boaring holiday and are stopping in the Iglika Palace
Just remember if you take £££ make sure the notes are not marked or ripped. I took £80 out to start with. £60 (3x 20s) were refused as they had pen marks on them. I withdrew cash from the ATM (I'm with HSBC) and they only charged me about £1.50 for every withdraw and I got a rate of 2.74.
Ok guys listen to uncle Kel,
the best exchange rate i was offerd in england was 2.54 lev to £1.
if you exchange with the bank in borovets at the bottom gondala station the rate is 2.7 lev to £1.
choice is yours.
