Read what other Viator.com travelers think about the Private Half-Day Tour: Istanbul's Two Continents. What they loved, what they liked and what they think could be improved, it's all here to help you make the most of your next trip.
The actual trip to the Dolmabache palace, harem and over to the Asian side, Camlica hill was very interesting and the palace was certainly filled with "baccarat cystal" at every turn. Unfortunately our guide did not appear to be that interested in telling us "tidbits" of info about what we were seeing and did not seem to be aware that we had people in our party who could not race along and climb stairs easily. He only spoke to those at the front of the group. So while I recommend the tour, I would suggest ensuring your guide is suited to your group and your group's "thirst" for knowledge of what you are seeing.
