Luckily, Ciwan was off the first two days of my stay, and we went out in the evening. We had a good talk, and he even invited me for lunch. I felt like I was visiting my friend's flat in Istanbul. He was truly a great host.
One thing I was really impressed with about his place was it was kept very clean, which made my stay more pleasant.
Thanks very much for your hospitality, Ciwan. Hope to see you again!
