Our B&B in Ljubljana was right at the Old Town. So once we stepped outside the building, we were directly on the old cobblestone street that runs parallel to the river. This is now a large and long shopping and restaurant area, and visitors typically spend their time walking up and down this street. The names change as there are multiple sections, but practically they are all linked together as one street running more or less on a north-south direction.
As much as it has the potential to be touristy, it isn't. Or at least it didn't feel too artificial. There were tourists, but it didn't feel like it was a crowd. Perhaps many people just haven't heard how cool Ljubljana is, so they aren't visiting. In any case, this area of town is where you do your shopping and eating. We ourselves went into several shops looking for souvenirs and other gifts. And the restaurants here were recommendable and not like tourist traps. There are no restaurant staff trying to entice tourists from the streets to go inside and consume expensive average-tasting food.
At night, this area is well-lit, and even though there are plenty of bars and pubs, those are more to the area directly in front of the river, and nevertheless, the noise level isn't high. Ljubljana isn't a party town yet, and hopefully it stays that way.
Finally, west of the Old Town across the river is where the country's government buildings are. There is also the university, which we explored a little bit. We also went to the National Library. This area is more residential, with large palatial buildings interspersed with villas and large houses. According to our guide in the boat tour we took, this area is where the diplomats live.
I have one last article waiting for Slovenia, which covers the castle. Stay tuned for that.
