We traveled to Sarajevo in November, 2011, and based on the reviews here, contacted Sarajevo Funky Tours to set up a couple of tours. Our trip was a bit last minute, but Skender was very accommodating, and we ended up joining another small group on the Total Siege Tour on one day, and then doing the Old Town tour the second day.
The Siege tour was amazing, with access to locations and sites that we never would have visited on our own. But more importantly, we would not have understood the significance of the sites or put them in context without Skender's remarkable narrative of the war. In general, we aren't big fans of tours, preferring to go places on our own, but in this case, it really was more like touring with someone we already knew, and who happened to be an expert in the local history. Skender is bright, personable, and very engaging, and we enjoyed the tour tremendously.
The next day, we went on a second tour - just the three of us, to see the Sarajevo Old Town (Baščaršija) by foot. We had already walked through the town on our own, but going through with Skender was a whole different experience, as he showed us many things we missed and took us to places we had walked by, but not really "seen" or understood. The library was a real highlight - I never would have thought to go inside to see the exhibits there. We also enjoyed visiting the Imperial Mosque and learning more about the Islamic faith. Sarajevo is remarkable that it has so many different religions represented in a small area, and one of the highlights of this tour was visiting the worship spaces of each of them - an Islamic mosque, a Catholic cathedral, an Orthodox church and a Jewish synagogue. Despite it's bloody history, Sarajevo has been very tolerant of religious differences, and this was one of the themes of the tour.
I know it will take me a long time to absorb all I learned and saw on this tour - it was a remarkable experience, and would not be the same without Skender's expertise. Highly recommended!
