We booked this spontaneously 45 minutes before the start and had no problems. You could also buy the trip directly at the tourist Info, where you have to meet.
We had a funny and lovely guide which name started with an M, but for the life of me i can't remember. She was knowledgeable, interacted with all the tour "members" - we were around 13 people -, and made us feel special (which is nice since the tour itself is not tailored and rather "standard-y", but that is totally fine for the price!!).
We are very happy we did the tour and didn't just roam around aimlessly. For us, this being the first time in Ljubljana, it was a nice small walk with interesting information varying from architecture, history, general slovenian life to fun facts. Easy to digest info with an enthusiastic guide!
Just be aware that even though it says you can bring dogs, they are not allowed on the funicular and in some buildings, so you'd have to miss out on those.
If there was a "second part" with more in depth info or a bigger walking radius, we would book it for sure the next time!
