Hikmet is a wonderful host. We arrived very late - almost 3 Am but he was up and ready for us. The place is lovely and all the main tourist spots are all walking distance away. Our bags were misplaced but Lufthansa and arrived at 1.30 Am next day and Hikmet was awake again. Very friendly and nice host. He did offer to arrange tours but my son's friend was in Istanbul and hence we declined the arranged tours.
We had a lovely time in Istanbul.
