Giurgiu

Giurgiu is a border town in Romania, very close to the Ruse-Giurgiu border crossing.

You can go to Giurgiu by train from Bucureşti but if you get there in the evening you'll have a hard time getting anywhere. The train station is not close to the town center. You might be better of taking the train to Ruse instead, since the train is going all the way to Sofia.
