Erkan is an awesome guide. She knows how to get around without having us wait in the long lines that most other tours had to wait in. One of my highlights and I think this is most of our group is Mary's House and we were able to spend a long time there before the crowds arrived. Erkan is generous with her time. We were with her for many hours and saw so many sites it was hard to keep up with all the history. Highly recommend!
