We did the classic and alternative tour with Circle and both guides, Emine and Ozcan were excellent with in-depth knowledge of the city and the culture. The small group worked very well and I enjoyed both days which passed very quickly. We also asked Circle to arrange our accommodation and transfers to and from the airport and once again this worked perfectly even when we gave the wrong details for our return flight !
This is a very professional company which is a good example of how it should be done, within the tourist industry, to promote a country.

Well done.
