Oğuz guided me along some of the less touristic places in the old town of Istanbul. He provided intelligent company with knowledge of the history thay he was eager to share. By means of a visit to the tile museum, we could climb the old city walls that was our actual target. And while baffled with the quest for a good vegatarian place to have lunch, we stumbled upon the best vegan place I could think of. He introduced me to Kadiköy as well, stimulating me to continue my day visit there with a climb of the tower and further exploring the sprawling streets around.
