Hakan was a great host. I stayed at his place for 2 days (29-30 April 2022). He arranged for my pick-up from the airport and welcomed me after midnight. He also guided me to get some basics from a supermarket which opens 24x7. The location was a bit far from Istiklal street, but I found that to be an advantage as I was able to open the window at night for a good night sleep away from all the noise. Would definitely do it again!
