we just returned from a tour of turkey, where celal (gerardo) was our guide for five days. he was very professional, well knowledged about all aspects of turkish history, he gave us all the information we asked for. his tours at various sites were just wonderful, you can tell he loves his job, and is fully prepared for everything. doesn't bore you at all with too much information, but rather slowly opens your eyes and heart to his country. i would love to go back to turkey, and have celal for my guide again.
