BEWARE, THEY ARE THIEVES:
I exchanged a few euros at Bullevard Vitosha 23 (not in Google maps) and a rude blond girl tryed to stash my change, when I noticed she tryed to steal me, she immediately put my change in the desk. If I was distracted she could have stolen my money.
Don't go to this place, there a lot of better exchange offices near by.
Very nice office. Fast service and courteous staff.
