Ljubljana
We just visited Ljublana as a stopover on our way to Bled, but it ended up being a super pretty city with nice canals and streets. The bus trip had really nice scenery on the way in also. The hostel we stayed out was in the middle of a busy street in the old town and was a bit bizarre really, as it was really quiet inside and they you step out the front door in the middle of a super busy lane-way with a view up to the castle.
First up, we got a funicular up to the castle which had nice views. Then walked back down and just walked around the old town and canals. For dinner we had a really nice blue vein cheese pizza out the front of the canal.
