Istanbul is a very beautiful city, and there are many places to visit, but it's also very big and for a first time traveler to Istanbul it can be hard to find all the good places. I highly recommend Hatice as a tour guide. She was very effective and informative, and she's a very kind and caring person. I had a tour with Hatice on my first day and since Hatice were so thorough, based on information she gave, the rest of my vacation were very good. I highly recommend City Highlights Private Walk with her.
