Can you give any info on where in borovets you got the rate? Was there any commission or additional fees for the transaction? And was that for cash, credit card, travelers cheque etc?
It was for cash. In any of the proper banks - two i used were the one inside the gondola station and one on the way up the hill past the turning to the gondola. The rates do change daily though but it never dropped below 2.80 for cash
