I consider Umut as a friend rather than host. He helped me with an official work and came with me for hours. Without his help, I could never do this. He is an amazing host too, as he constantly checks what you may need. When I arrived, I was surprisingly found that he is waiting for me at the Metro station, and invited me for dinner. It was a wonderful experience for me. (I did not write about the house, as he is moving)
