I cant believe that you actually have lived in Sofia for 2 years and you don't know anything about it...This is ridiculous in my opinion. I don't want to insult you but it seems like you don't know anything about European culture...  And this video is made for people like you, so I strongly advise you to take your time and watch it again and maybe watch some similar ones for other EU cities, which will give you some background knowledge. Finally, if you don't like Sofia and don't know anything about it, why would you live here?
( ps. things said in the video are all true, but maybe its strange for you that Constantine liked Sofia not Walla Walla? :S )
