We traveled to Istanbul in May and decided to hire a guide from City of Sultans for our first day. I had read great reviews about Eren Bolek, one of their English-speaking guides, and I requested him specifically. Eren arrived at our hotel for our day-long tour promptly and was warm and friendly. He took us to the Hippodrome, Hagia... More

Four days with Eren Bolek was barely enough time to explore Istanbul. The City of Sultan tours was a fantastic experience from the airport pick up to the return trip to the airport. And on time considering Istanbul traffic! Eren is a wealth of knowledge of Turkish history and culture. We never waited in long lines because Eren seemed to... More

We only had two days in this magnificent city so we needed to spend our time wisely. We selected City of Sultan tours based on previous reviews, and are very fortunate we did. Their people are prompt and courteous, from the gentleman who meets you at the airport and transfers you to your hotel, to your guide and driver who... More

Where do I begin... We booked our flights in June of 2012 for our trip in May of 2013. Then I started researching for a tour company that could offer us what we wanted for a small group tour for about 10 days. I came upon COS (City of Sultans) and decided based on all the wonderful reviews that we... More

I am a traveller and this was my first time visit to Istanbul with my collegues. We have chosen City Of Sultans by an advise of my mother-in-law who has used City of sultans services in Istanbul last year. First of all I advise you to request Eren Bolek as your tour guide. He cares about all your requests and... More

We booked a three day tour including transfers to and from the airport. The primary purpose of our trip was learn about the history and culture of... More

We were on a family trip of 10 adults / 7 children and had prearranged a private tour of Istanbul through a US-based travel coordinator. Eren Bolek from City of Sultans was our guide for the two days and he was excellent. He was very knowledgeable and explained the sites from all perspectives: historic, political, religious. Eren was able to... More

This is a great company from what I can tell. I took a day tour with Eren and he was amazing showing me all of the old town and highlighting all the best sights. We did not have to wait in any lines as he was very well connected. On the 2nd day, apparently City of Sultans let another company... More

We were a group of 4 and booked the 5 day tour including transfers, hotel and 2.5 day program. We were very happy with the organization of the tour. I organized everything with Ozgur and he was extremely courteous and helpful getting everything set up for our trip. Our airport transfer person Gokay was also on time and informative, even... More
