I stayed here for four nights, and it was a very comfortable base for exploring Istanbul. I especially liked the living room/kitchen table, which offered a quiet spot to relax before going out into the frenzy of Taksim square. Hasan was not in town for most of the time I was there and instead another airbnb'er (who was polite and friendly) was staying in the other bedroom. I did get a chance to meet Hasan on the last day, and he was very friendly -- it was fun to hear some of his stories...and to hear him singing!
