This tour was a highlight of our trip. Semih is so incredibly knowledgeable about the history of Istanbul/Constantinople and its historical sites. He answered every question we had and was very flexible with his itinerary. He met us early so we could beat the crowds and he was very keen to ensure that every one of our group of 12 (ranging in age from 16 years to 76 years) was engaged and catered for. We toured the Blue Mosque, Hippodrome, Topkapi Palace, Basilica Cistern and the Spice Market. Semih also suggested a particular restaurant for lunch that we would never have found by ourselves - and they provide a banquet lunch that most of us rated the best meal we had on our 3-week trip! Delicious authentic Turkish cuisine. We absolutely loved Semih's tour and could not recommend him highly enough. Thanks Semih - from your Aussie friends :)
