We (couple late twenties) went for this after reading all the reviews.
We did 9am till noonish (maybe longer), covering the Tunnel Museum and the siege tour. We went with just another couple. Skender, the guide, drove us out to the Tunnel museum, the whole way detailing the start of the war - giving the political and economic background (he has a Masters in Economics).
The Tunnel Museum was fantastic, and Skender was able to give us a real insight into the lives of Sarajevans who lived through the siege - made all the more relevant to me hearing it from someone two years my junior. He was able to recant both witty and interesting anecdotes, as well as pouring mountains of fascinating facts, figures and other details onto us, giving the full history of the tunnel (which itself is really cool to walk through).
We were then taken to a nearby mountain-top overlooking Sarajevo, and walk around a semi-destroyed building used by the Serbs to house tanks and soldiers. Really good place for photos.
On our way back Skender dropped us off on the 1984 Olympics Toboggan run - we spent 10 minutes walking down to the bottom where Skender was waiting to pick us up.
We were charged 20 Euros each, but gave a ten Euro tip because it was so brilliant.
It's a truly worthwhile way to spend some time in Sarajevo, and to learn about pre-siege, siege, and post-siege life, politics and society. I would strongly recommend this tour to anyone who goes.
