A lot of people here don't speak English. I recommend you to visit the Info point , located on the "Iskra" street. To do this, you have to walk the distance from the Railstation: go straightforward to the square and walk again in the same direction.
Of course, the young people speak English very good, but don't rely on that. Try to learn some useful phrases in advance, as well as the cyrillic alphabet.
Look out for dogs!!
There seem to be plenty of stray dogs in more or less every Bularian town or village. Look out for them since many of them are mentally disturbed due to inbreeding! I have seen them attacking cars in the streets!!
