This is mostly the question of tastes. I lived in Sofia for two months, mostly in the city center. For me an international mobility is important and I don't drive, so the well connected airport and good means of transportation towards it were paramount. Thus Plovdiv and also Varna and Burgas are not an option for me. But from the business perspective it is a real tax haven. Also, there is an IT community there, and offices of large companies including Microsoft and Uber.
